## Posts

- [Can You Freeze Bread?](https://willitruinit.com/can-you-freeze-bread/): Yes, and the freezer beats the fridge by a mile. Why bread stales fastest at fridge temperature, and how to bring a crust back.
- [Can You Freeze Mashed Potatoes?](https://willitruinit.com/can-you-freeze-mashed-potatoes/): Yes, if it is rich. Butter and cream stop the starch separating; plain mash thaws grainy. How to bring the texture back.
- [Can You Freeze Butter?](https://willitruinit.com/can-you-freeze-butter/): Yes, for a year, with no texture change. Wrap it well so it does not absorb smells, and grate it frozen for pastry.
- [Can You Freeze Soup in Glass Jars?](https://willitruinit.com/freeze-soup-glass-jars/): Yes, with an inch of headspace and straight-sided jars. The two reasons jars break, and why cooling first matters.
- [Can You Freeze Lettuce and Salad Greens?](https://willitruinit.com/can-you-freeze-lettuce/): Not for salad, ever. Why lettuce thaws slimy, which greens do freeze well, and the ice water trick for limp leaves.
- [Can You Freeze Bananas?](https://willitruinit.com/can-you-freeze-bananas/): Yes, up to six months, and it is the best use for overripe ones. Peel them first, because frozen skins never come off.
- [Can You Freeze Eggs?](https://willitruinit.com/can-you-freeze-eggs/): Out of the shell, yes, for up to a year. In the shell, never. Plus the salt trick that stops yolks turning gluey.
- [Can You Microwave Grapes?](https://willitruinit.com/microwave-grapes/): No. Two grape halves touching create plasma, which is a documented physics quirk that destroys microwaves and starts fires.
- [Can You Microwave Parchment Paper?](https://willitruinit.com/microwave-parchment-paper/): Yes, and it beats cling film. Why parchment is safe, how to steam in it, and the two papers it gets confused with.
- [Can You Microwave Mason Jars?](https://willitruinit.com/microwave-mason-jars/): Glass yes, briefly and gently. Lid never. Why mason jars crack more easily than Pyrex, and the pressure risk nobody mentions.
- [Can You Microwave Cardboard and Pizza Boxes?](https://willitruinit.com/microwave-cardboard-pizza-box/): No. Dry cardboard scorches, and the coatings, glue seams and metallic sleeves are worse. How to reheat pizza properly instead.
- [Can You Microwave Water to Boil It?](https://willitruinit.com/microwave-water-boiling/): Yes, but superheating is real: water can pass boiling point without bubbling, then erupt when you touch it. The wooden stirrer fix.
- [Can You Microwave Paper Plates?](https://willitruinit.com/microwave-paper-plates/): Plain ones, briefly, yes. Why the glossy and printed ones are the problem, and what makes a plate collapse.
- [Can You Microwave Plastic Containers?](https://willitruinit.com/microwave-plastic-containers/): Only if it says so, and not with oily food. What the microwave safe symbol actually tests, and what it does not.
- [Can You Put Silicone in the Dishwasher?](https://willitruinit.com/silicone-dishwasher/): Yes, genuinely. The only quirks: it comes out greasy and holds smells, and both have a simple fix.
- [Can You Put Copper Pans in the Dishwasher?](https://willitruinit.com/copper-pans-dishwasher/): No. One cycle turns it dull brown, and on lined pans the detergent attacks the lining and rivets. The polish that fixes tarnish.
- [Can You Put Plastic Containers in the Dishwasher?](https://willitruinit.com/plastic-containers-dishwasher/): Top rack only. Why the bottom rack warps lids, what makes plastic go cloudy, and the sunlight trick for tomato stains.
- [Can You Put an Air Fryer Basket in the Dishwasher?](https://willitruinit.com/air-fryer-basket-dishwasher/): Usually labelled safe, but the manual still says hand wash. The ten minute soak that beats a cycle without costing you the coating.
- [Can You Put Wine Glasses and Crystal in the Dishwasher?](https://willitruinit.com/wine-glasses-crystal-dishwasher/): Everyday glasses usually yes, lead crystal no. The difference between cloudiness that wipes off and cloudiness that is permanent.
- [Can You Put a Yeti or Stanley in the Dishwasher?](https://willitruinit.com/insulated-tumbler-dishwasher/): Most current models yes, older ones no. Check the base, split the lid, and what a sweating cup means.
- [Can You Put Knives in the Dishwasher?](https://willitruinit.com/knives-in-dishwasher/): No. Detergent dulls the edge, heat loosens handles, and knocking chips the blade. The ten-second alternative.
- [Can You Put Toothpicks and Skewers in an Air Fryer?](https://willitruinit.com/toothpicks-skewers-air-fryer/): Metal is fine, wood needs a twenty minute soak. Why dry exposed wood scorches in a convection basket.
- [Can You Put Ceramic Dishes in an Air Fryer?](https://willitruinit.com/ceramic-in-air-fryer/): Oven-safe ceramic only, at room temperature, with airflow around it. Why dishes crack, and when ceramic beats metal.
- [Can You Use Cooking Spray in an Air Fryer?](https://willitruinit.com/cooking-spray-air-fryer/): Oil yes, aerosol no. Why Pam-style sprays leave a sticky film that ruins the coating, and what to use instead.
- [Can You Put Wet Batter in an Air Fryer?](https://willitruinit.com/wet-batter-air-fryer/): No. Batter drips through before it sets, leaving bare food and burnt drips. The breading method that actually works instead.
- [Can You Put Frozen Food Straight in an Air Fryer?](https://willitruinit.com/frozen-food-air-fryer/): Yes, straight from frozen, and it beats thawing. Times, temperatures, and the one mistake that makes everything soggy.
- [Can You Put Paper Towels in an Air Fryer?](https://willitruinit.com/paper-towels-air-fryer/): No. The fan lifts it, and paper ignites at around 450F. The most common cause of air fryer fires, and what to use instead.
- [Can You Freeze Cheese?](https://willitruinit.com/can-you-freeze-cheese/): Hard cheese yes, soft cheese no. What comes back crumbly, what separates for good, and why grating first is the trick.
- [Can You Freeze Cooked Rice?](https://willitruinit.com/can-you-freeze-cooked-rice/): Yes, and it reheats better than fridge rice. The rule that actually matters: cool it within an hour, freeze it flat, reheat once.
- [Can You Freeze Milk?](https://willitruinit.com/can-you-freeze-milk/): Yes, up to three months. It separates and looks grainy when thawed, which is harmless. How to freeze it without splitting the jug.
- [Can You Microwave Eggs in the Shell?](https://willitruinit.com/microwave-eggs-in-shell/): Never. Steam builds inside the shell and it bursts, sometimes after you take it out. The safe way to microwave an egg instead.
- [Can You Microwave Styrofoam?](https://willitruinit.com/microwave-styrofoam/): Only if it is labelled microwave safe, and most takeaway foam is not. Why greasy food makes it worse, and what to use instead.
- [Can You Put Aluminum Foil in the Microwave?](https://willitruinit.com/aluminum-foil-microwave/): No. Microwaves reflect off metal and arc at thin edges, which sparks and can start a fire. The ready-meal exception explained.
- [Can You Put Wooden Spoons and Cutting Boards in the Dishwasher?](https://willitruinit.com/wood-in-dishwasher/): No. An hour of soaking then dry heat swells and shrinks the wood, which splits boards and raises the grain on spoons.
- [Can You Put Non-Stick Pans in the Dishwasher?](https://willitruinit.com/nonstick-pans-dishwasher/): The label says dishwasher safe. It means the pan survives, not the coating. Why hand washing triples how long non-stick lasts.
- [Can You Put Cast Iron in the Dishwasher?](https://willitruinit.com/cast-iron-dishwasher/): Never. Detergent strips the seasoning and the pan sits wet, so it comes out grey and rusting. What to do instead, in ninety seconds.
- [Can You Put Plastic in an Air Fryer?](https://willitruinit.com/plastic-in-air-fryer/): No, and there is no exception worth it. Air fryers run at 350F to 400F; food plastics soften from about 150F.
- [Can You Put Glass in an Air Fryer?](https://willitruinit.com/glass-in-air-fryer/): Only oven-safe borosilicate, at room temperature, with clearance. Why air fryers crack glass that an oven never would.
- [Can You Put Parchment Paper in an Air Fryer?](https://willitruinit.com/parchment-paper-air-fryer/): Yes, and manuals prefer it to foil. The rules: food on top, never empty, never during preheat, and buy the perforated kind.
- [Can You Put Aluminum Foil in an Air Fryer?](https://willitruinit.com/aluminum-foil-air-fryer/): Yes, with rules. Foil is safe in an air fryer when food holds it down and it never touches the element. What goes wrong, and what to use instead.
