Ingredients

  • 4 cups all-purpose flour, spooned and leveled (500 g), plus more for the counter
    Swaps for all-purpose flour

    Instead of all-purpose flour

    • Gluten-free 1:1 baking flour: The same amount, a blend that includes xanthan gum. A little grittier and more crumbly, browns faster and dries out sooner.
    • Bread flour: The same amount. More gluten: chewier cookies and bread, tougher cakes.
    • Whole wheat flour: Up to half of the flour. Nuttier, darker and denser.

  • 1 tsp baking soda
    Swaps for baking soda

    Instead of baking soda

    • Baking powder: 3 tsp baking powder for each 1 tsp baking soda. It rises, but bakes come out paler and puffier, cookies spread less, and the extra powder can taste a little bitter.

    More for baking soda

  • 1 tsp kosher salt
    Swaps for kosher salt

    Instead of salt

    • Table salt or fine sea salt: About half as much as Diamond Crystal kosher, about ¾ as much as Morton kosher. The same saltiness when measured this way.
    • Salt by weight: 1 tsp is about 6 grams of table salt, 5 grams of Morton kosher, 3 grams of Diamond Crystal kosher. The most reliable way to swap, especially in baking and brines.

    More for salt

  • 1 tbsp granulated sugar (optional)
    Swaps for granulated sugar

    Instead of sugar

    • Less sugar: Up to ¼ less in cookies, muffins and quick breads. Less browning and spread, a drier, more cake-like texture, and bakes go stale sooner.
    • Brown sugar: The same amount, packed. Moister and chewier, with a caramel flavor and darker color.
    • Coconut sugar: The same amount. Darker and caramel-like, a little less sweet; cookies spread slightly less.

    All 4 swaps for sugar

  • 1 ¾ cups buttermilk, cold (415 ml), plus 1 to 2 tbsp if needed
    Swaps for buttermilk

    Instead of buttermilk

    • Milk + lemon juice or vinegar: 1 tbsp lemon juice or white vinegar in a measuring cup, topped up with milk to 1 cup, for each cup. Thinner and a bit less tangy, so bakes are a touch less tender.
    • Plain yogurt + milk: ¾ cup plain yogurt + ¼ cup milk for each cup (with Greek yogurt: ½ cup + ½ cup). The closest match for tang and thickness.
    • Plain kefir: The same amount. Similar tang, a little thinner.

Steps

Kid helper. A child can do steps 2, 3, 4, 5 and 6: no knife, no heat. Steps marked “Grown-up” use a knife or heat. Cooking with kids

  1. Heat the oven to 425°F (220°C).
    Line (how to line a pan) Line a pan Cover the bottom (and sometimes sides) of a pan with parchment or foil so food doesn't stick and lifts out easily. 1. For a sheet pan, tear parchment the size of the pan and lay it flat.2. For a round cake pan, trace the bottom on parchment, cut the circle out and press it in.3. For brownies and bars, leave two long sides hanging over to make handles (a "sling").4. A little grease under the paper holds it in place. Done when: The paper lies flat with no folds where the batter could run under it. How to line a baking pan with parchment: mistakes to avoid

Hold the whisk loosely and move it in quick circles or side to side, touching the bottom.3. For lumpy mixtures, add liquid a little at a time and whisk after each.4. For sauces on the stove, keep the whisk moving across the whole bottom of the pan. Done when: The mixture is even with no lumps or streaks of egg. How to whisk: mistakes to avoid

  5. Tip the dough onto a floured counter and fold it over itself 4 or 5 times, just until it holds together. Do not
    knead (how to knead) Knead Work bread dough by pressing, folding and turning it to build the gluten that gives bread its chew. 1. Turn the dough onto a lightly floured counter.2. Push it away from you with the heel of your hand.3. Fold it back over itself toward you.4. Turn it a quarter turn and repeat, in a steady rhythm.5. Add flour only a little at a time, if it really sticks.6. In a stand mixer, use the dough hook on medium-low. Done when: The dough is smooth and springs back when poked; a small piece stretches thin enough to see light through (8 to 10 minutes by hand). How to knead bread dough: mistakes to avoid

Tips

  • Mix gently and quickly. The baking soda starts working as soon as it meets the buttermilk, so get it into the oven right away.
  • No buttermilk? Stir 1 1/2 tablespoons of lemon juice into 1 3/4 cups of milk and let it sit 5 minutes.
  • For a sweet version, add 3/4 cup raisins and 2 more tablespoons of sugar to the dry ingredients.

Storage

Best the day it is made. Wrap and keep at room temperature up to 2 days; it toasts beautifully.
