Made In Cookware® - The Cookware Chefs Actually Use
Plenty of cookware brands will pay a famous chef to hold a pan and smile. Made In doesn't do that. Their cookware is used in 4,000+ professional kitchens and has been adopted by millions of home cooks.
Now you can cook with the exact pieces from your favorite restaurant at home. Every piece of cookware is built by craftsmen in the USA and Europe, using performance materials and construction that hold up to the rigors of the world’s most demanding kitchens. There’s a reason why it’s the cookware with the most 5-star reviews on the internet.
Most people who need a full kitchen replacement start with their Cookware Sets, where you’ll find their best deals. Pasta lovers need the 3 QT Saucier, the piece chefs call their most-reached-for pan and is the pan that powers world-famous Italian joints like Mother Wolf in L.A.
Good morning.
7 new guides went live since Monday, and if there is a thread running through them, it is arithmetic. Not the scary kind. The kind where one number you did not know quietly decides whether the thing in your closet actually works: how much a child can carry, how hot a pressure canner has to get, how long you hold pressure on a cut before you look.
3 quick things this week
A loaded pack for a child tops out at 15 percent of body weight, per the American Academy of Pediatrics. For a 40 pound kid that is 6 pounds, everything included, and 1 liter of water is 2.2 of them.
Boiling water can never safely can green beans. It stops at 212 degrees F at sea level no matter how long you leave it, and botulinum spores need 240. That gap is the whole reason a pressure canner exists.
Direct pressure on a bleeding cut means 10 full minutes without peeking. Lifting the gauze at minute 4 to check does not give you information. It restarts the clock.
This week
This is the stretch of August where a garden stops being a hobby and starts being a delivery schedule. Two of this week's guides landed on purpose: what to do with the good half of the harvest, and what to do with the rest of it.
If you only pick up one job, get your canner's dial gauge tested. Many county extension offices still do it, often free, and it takes about 10 minutes. A gauge reading 2 pounds off is one of the quietest ways to lose a whole load, because nothing looks wrong at any point.
Emergency Kit for Kids
Here is the test this one opens with. Hand the kit to your child and ask them to open it. Most kits fail right there. The zipper is stiff, the flashlight wants two hands, and the food is something they have never agreed to eat on a good day.
Then there is the math, which reorders everything else. The American Academy of Pediatrics caps a loaded backpack at 15 percent of body weight. For a 40 pound child that is 6 pounds total, and a single liter of water takes 2.2 of it. Every other item suddenly has to earn its spot.
Inside: the full weight table by child size, the 3 cheapest items that do the most work, why water is the one problem a kid's kit cannot fully solve, and the age below which a pack stops helping and starts being a trip hazard.
Pressure Canning Vegetables
One number sits at the center of this guide and settles an argument that has been running in comment sections for years. Water boils at 212 degrees F at sea level and it will not climb higher no matter how patient you are. The spores that cause botulism need 240. Everything a pressure canner does, it does to close that gap.
The rest of the guide is about the steps that actually spoil batches, and it is not the jars or the gauge. It is 3 points in the sequence that feel optional and are not. One of them asks you to wait 10 minutes while it looks like nothing at all is happening.
Inside: USDA tested times and pressures for beans, carrots, beets, potatoes and squash, how those numbers shift with your elevation, the weighted gauge quirk that pushes some households straight to 15 pounds, and the 2 vegetable preparations that have no safe home process at any pressure.
First Aid for Common Household Injuries
Most of what people know about burns is half right. Cool water yes, ice no, butter definitely not. What usually gets left out is the timing, and the size threshold where you stop treating it at the sink and start driving.
The cuts section holds the detail I think about most often. Firm direct pressure for 10 full minutes, and the word carrying the weight there is full. There is also a depth, measured in fractions of an inch, past which a cut is not yours to close.
Inside: the exact numbers from Mayo Clinic, MedlinePlus and the American Heart Association for burns, cuts, sprains and choking, including the AHA's 2025 update and its first ever guidance for adult choking, plus the counterintuitive reason a serious burn can hurt less than a minor one.
How to Test Water Quality in Storage Tanks
Stored water never announces the day it goes bad. It looks the same on day 400 as it did on day 4, which is why the honest answer to "is this still drinkable" is a short list of numbers rather than a look and a sniff.
There are 5 of them. Two are bacteria, and the acceptable level for both is zero with no qualifiers attached. The others carry EPA thresholds, and one of those behaves in a way that catches people out, because the standard fix everybody reaches for first makes it worse instead of better.
Inside: what to test for and how often, why a home test strip is a screening tool and not an answer, the 12 hour rule that makes a lead sample valid, how quickly a bacteria sample has to reach the lab, and the 5 events that should send you testing immediately no matter what the calendar says.
Pet Emergency Kit Checklist
The item that decides whether your dog gets through the door of an evacuation center is not the leash and it is not the food. It is a piece of paper, and it is much better to learn that now than in a parking lot at 11 at night.
The supply numbers are also larger than most people plan for. CDC's target is 2 weeks of food per animal and at least 7 days of water, which for a 60 pound dog lands somewhere around a 25 pound bag. AVMA and ASPCA put the line in slightly different places, so the guide sets all 3 side by side and lets you choose.
Inside: the full checklist, what the PETS Act does and does not actually guarantee, the carrier habit worth building now so your cat will get in it later, and why the photo in your kit needs to have you in it too.
How to Read a Topographic Map
A topo sheet is already telling you how steep the next mile gets, how far it really is, and where the easy line through the ridge sits. Most of us just never learned to hear it.
It starts with one number printed in the margin that most hikers walk straight past. Get that, plus the thicker labeled line every fifth contour, and the spacing between lines stops being decoration and turns into slope you can put a percentage on. There is a trick for reading which way a stream runs, too, using nothing but the shape of the lines where they cross it.
Inside: contour intervals and the terrain they quietly hide, how to convert line spacing into an actual grade, what 1:24,000 means in feet you can picture, why the declination diagram goes stale, and the one thing a topo map will never tell you about a blue line creek in August.
Home Composting Methods
5 methods, and the one most of us are quietly already doing (pile it up, walk away, wait) turns out not to be the lazy version of the others. It makes a genuinely different product, and there is a real argument for choosing it on purpose.
The hot pile is the one with rules. It needs a minimum mass, roughly a 3 foot cube, or it cannot insulate its own core and simply will not cook. Above one internal temperature it kills weed seeds and pathogens. Push a little past that and it starts killing the organisms doing the work for you.
Inside: all 5 methods with their honest tradeoffs, the browns to greens ratio that actually matters and the carbon numbers behind it (cardboard is nowhere near what you would guess), how many pounds of scraps a worm bin really handles in a week, and the short list of things that never go in any of them.
One picture, one gap
Most kit lists are an exercise in addition. This one is subtraction, which is a very different job. The gap it exposes is water. At 2.2 pounds a liter, a child's whole allowance disappears fast, and our guide is honest that this is the piece a kid's kit cannot fully solve by itself. Worth a screenshot before you pack.
Worth a watch
This one pairs with the household injuries guide. Our article tells you to hold firm pressure for 10 full minutes and covers the point where a cut needs professional closure. What it does not cover, because it is a separate subject, is what happens over the next 3 days if that cut goes wrong.
Joe Alton, MD, and Amy Alton, ARNP, have been publishing survival medicine as Doom and Bloom for well over a decade. Their video Wound Treatment and Infection Control is a calm walkthrough of what an infected wound actually looks like as it turns, and what you do about it when a clinic is not an option. It is the next question our article raises, answered by people qualified to answer it.
Before you go
That is the week. 7 guides, one from each of our 7 subject areas, which is how we are trying to run these now, so there is always something waiting wherever you happen to be in this.
If somebody forwarded this to you and you would like it landing in your own inbox twice a week, subscribe here. It is free, and it stays practical.
And if you are already on the list, pick one item off the 3 quick things and go handle it today. Weighing your kid's backpack takes about 2 minutes.
You never know, but you can always be ready.
