  • These figures use the US cup (240 ml). A metric cup is slightly larger at 250 ml, so it holds a little more. Use the metric cup converter →
  • Cup sizes are not standard worldwide, so the same cup of an ingredient can weigh more or less depending on the country. What is a cup measurement →
  • A teaspoon here is the 5 ml standard, the same in the UK, Europe, and Australia. A US teaspoon is fractionally smaller at about 4.9 ml. When teaspoon size matters →
  • A little over or under won't ruin the bake, though it can nudge the final taste or colour.

Instant yeast is a finely milled dry yeast that mixes straight into dry ingredients without proofing first. One metric cup (250 ml) of instant yeast weighs around 150 grams or 5.29 ounces, though recipes almost always measure it by the teaspoon or sachet (a 7 g sachet equals about 2 1/3 teaspoons). It is the quickest route to a reliable rise in bread, pizza dough, and cinnamon rolls.

Yeast amounts are tiny but matter a lot: too little gives a dense loaf, too much an over-proofed one with a yeasty taste. Weighing in grams is far more accurate than scooping a teaspoon, especially when scaling a recipe up or down.

Also known as

  • fast-acting yeast
  • rapid rise yeast
  • bread machine yeast
  • quick yeast

Active dry yeast is granular and needs proofing in warm liquid before use, unlike instant yeast which goes straight into the dry mix. They are interchangeable 1:1 by weight, so the swap is about method rather than amount. See what 1 US cup of active dry yeast is in teaspoons.
