Put the potato chunks in a pot, cover with cold water by an inch and add 1 teaspoon salt.
on high, then gently lower in the eggs with a spoon and turn the heat to medium.
Bring to a boil. It means heating a liquid on high until it’s fully boiling before you move on. A lid on the pot gets it there faster, which makes it a good moment to chop something.
How you’ll know: Big bubbles break all over the surface, and they keep coming when you lift the lid.
High heat
Dolly’s tip: Lower them in slowly so they do not crack on the bottom of the pot.11 to 12 minutes, until a knife slides into a potato with no resistance.
Simmer. Simmering means keeping a liquid just below a boil, with small bubbles rising gently. It cooks food evenly and lets a sauce thicken without scorching on the bottom.
How you’ll know: Small, lazy bubbles break the surface every second or so, and nothing is churning.
Medium heatTimer: 11 min 30 sec
Food safety: For the safest eggs, cook until the whites are fully set and the yolks begin to thicken. Dishes made with eggs are done at 160°F.
Lift the eggs into a bowl of cold water. the potatoes and spread them on a plate to cool for 10 minutes.
Drain. Draining means pouring off liquid, like tipping pasta into a colander or spooning extra fat out of the pan. Pour hot grease into a can or jar, not the sink, where it hardens and clogs the pipes.
How you’ll know: Only a few drips are left, and the food isn’t sitting in a puddle.
Timer: 10 min
the oil, vinegar, pepper and the rest of the salt in a big bowl. Add the warm potatoes and gently.
Whisk. Whisking means beating quickly with a whisk or a fork to blend things together. It smooths out lumps and mixes eggs, oil or sauces evenly.
How you’ll know: It all looks one even color and texture, with no streaks or lumps.
Toss. Tossing means gently lifting and turning food so everything gets coated, like pasta in sauce or vegetables in oil. It coats every piece evenly without mashing anything.
How you’ll know: Every piece looks glossy or evenly coated, with no dry spots hiding underneath.
Dolly’s tip: Warm potatoes soak up the dressing, so every bite is seasoned all the way through.the bell pepper, the onion and dice the tomatoes, then add them to the bowl.
Dice. Dicing means cutting food into small, even cubes, usually a quarter to half an inch across. Pieces the same size cook at the same speed, so nothing burns while the rest catches up.
How you’ll know: Your pieces are little cubes about the size of a chickpea, and they all look close to the same.
Finely chop. Finely chopping means cutting food into small pieces, a little bigger than minced, about the size of a lentil. Small pieces spread their flavor through the dish and cook quickly.
How you’ll know: Nothing is bigger than a lentil, and the pile looks like confetti rather than paste.
Flake in the tuna in big chunks, add the olives and everything together gently.
Fold. Folding means mixing gently by scooping from the bottom and turning it over the top, instead of stirring hard. It keeps light mixtures airy and soft things like berries or herbs in one piece.
How you’ll know: You use slow, wide strokes and stop as soon as there are no streaks left.
Food safety: Rotisserie chicken, deli meat, canned tuna and cooked shrimp are already cooked. Keep them cold until you use them, and heat them until steaming hot if the recipe warms them.
and quarter the eggs, set them on top and scatter the parsley.
Peel. Peeling means removing the skin with a vegetable peeler or a small knife. It takes off tough or bitter skins, though potato and carrot skins are fine to leave on unless the recipe insists.
How you’ll know: The color underneath is even all over, with no patches of skin left behind.
Dolly’s tip: It keeps 3 days in the fridge and needs no reheating, so it is perfect for work. Let it sit out 10 minutes before eating so the olive oil softens.
