When making bread and other baked goods, yeast is one of the ingredients needed for rising the dough. The yeast is available in several forms such as FRESH, ACTIVE DRY or INSTANT yeast. It is very important to know how to use each of these forms and hot to swap one for another. In the text below find useful info about each kind of yeast.
Active dry yeast must be rehydrated in liquid before being added to the dough. The liquid could be water or milk with temperature of 43°C (110°F) - 46°C (115°F). It is not concentrated as instant yeast, so you need more active dry yeast when substituting.
Instant yeast, also known as fast-rising bread machine yeast is made into much finer particles. Instant yeast is usually more expensive and can be directly added to the dry ingredients without rehydrating or proofing first. You can use water that is somewhat hotter, 48°C (118°F) - 54°C (130°F), to make your dough unless the recipe calls for colder water.
Want to try recipes using instant dry yeast? Start with our simple homemade doughnuts or mini version filled with zesty lemon curd. Next, give it a try to our lemony sweet rolls with marzipan. For a savoury treat, try our recipes for garlic breadsticks loaded with cheese or crispy pesto twists.
Fresh yeast, also known as cake yeast or compressed yeast usually respond a bit quicker than active dry yeast. Fresh yeast is packed into small squares and it has a short shelf like of a few weeks, compared to months or even years for dried yeast.
Proof the fresh yeast by crumbling it into warm water 43°C (110°F) with a tablespoon of flour and sugar. Stir and wait for 10 minutes until it foam. To use fresh yeast in a recipe, you can make a well in the centre of the dry ingredients, crumble the fresh yeast into the middle, cover with warm liquids and stir up a little of the dry ingredients into the liquids. Wait until bubbles form.
You may find recipes using large amounts of fresh yeast which is not necessary. Simple bread recipes require 2% to 3% of the weight of flour. If you're using 1 kilo of flour, that means you need only 20 to 30 grams of fresh yeast.
Want to test recipes using a crumbly block of fresh yeast? We recommend our recipe for doughnuts filled with vanilla cream or crusty pizza with smoked ham and pumpkin.
