Steps
Tap an underlined word for a quick explanation.
the oven to 425°F. Cut the cauliflower into florets, the potato, cut the onion into wedges and the garlic.
Preheat. Preheating means turning the oven on before you start, so it’s fully hot when the food goes in. Food that starts in a cold oven cooks unevenly and doesn’t brown the same.
How you’ll know: The oven beeps or its light clicks off, usually 10 to 15 minutes after you turn it on.
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.
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.
Toss everything on a large with the oil and salt and spread it out.
Sheet pan. A sheet pan is a flat metal baking tray with a low rim all the way around. The rim catches juices, and the wide surface lets food spread out and brown.
How you’ll know: Everything fits in one layer with a little space between the pieces.
for 25 to 30 minutes, stirring once, until the cauliflower is golden at the edges and the potato is soft.
Roast. Roasting means cooking in a hot oven, around 400°F to 450°F, usually spread out on a sheet pan. The dry heat browns the outside and brings out sweetness, especially in vegetables.
How you’ll know: The edges are browned and a little crisp, and a fork slides easily into the thickest piece.
Timer: 27 min 30 sec
Scrape everything into a large pot with the water and bouillon cube, over medium heat and cook for 5 minutes.
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: 5 min
Mash with a potato masher until mostly smooth, then stir in the milk and mustard and heat until steaming. Don’t let it .
Boil. Boiling means heating a liquid until big bubbles rise and break all over the surface. It’s the fastest way to cook pasta, potatoes and eggs, because it’s as hot as water gets.
How you’ll know: Bubbles are breaking across the whole surface, not just at the edges, and steam is rising.
Low heat
Dolly’s tip: The roasted potato is what makes this thick and creamy without flour.Turn off the heat and stir in the cheddar a handful at a time until .
Melt. Melting means gently heating something solid, like butter or cheese, until it turns liquid. Low or medium heat keeps it from browning or burning.
How you’ll know: It’s smooth and liquid, and butter may foam a little but hasn’t turned brown.
Dolly’s tip: Grate the cheese yourself and add it off the heat for the smoothest soup.Add the pepper, taste for salt, and serve with chives on top.
