Types of Yeast and Their Uses
1. Active Dry Yeast
Active dry yeast is one of the most common yeasts used in home baking. It consists of granules of yeast that are dormant until activated by warm water.
Best Used For: Bread, pizza dough, cinnamon rolls, and most yeast-leavened baked goods.
How to Use: Must be dissolved in warm water (37-43°C) before mixing with dry ingredients.
Recipe Ideas:
2. Instant Yeast (Rapid Rise or Bread Machine Yeast)
Instant yeast is a more refined version of active dry yeast and does not need to be dissolved in water before use.
Best Used For: Any yeast-leavened bread that requires a faster rise.
How to Use: Can be mixed directly into dry ingredients without proofing.
Recipe Ideas:
3. Fresh Yeast (Cake Yeast or Compressed Yeast)
Fresh yeast is sold in small, moist blocks and has a short shelf life. It is commonly used by professional bakers. I keep mine in the freezer when I have it as the Thermomix is the perfect way to bring it to life with some warmth and liquid for just a minute. Freeze in ice cube sized blocks.
Best Used For: Pastries, brioche, croissants, and rich doughs.
How to Use: Needs to be crumbled and dissolved in warm liquid before mixing.
Recipe Ideas:
4. Wild Yeast (Sourdough Starter)
Wild yeast is naturally occurring and is cultivated through a sourdough starter, a mixture of flour and water that ferments over time.
Best Used For: Sourdough bread, pancakes, and fermented baked goods.
How to Use: Needs to be regularly fed and maintained to stay active.
Recipe Ideas:
5. Brewer's Yeast
Brewer's yeast is a byproduct of beer production and is used as a nutritional supplement rather than a leavening agent.
Best Used For: Beer brewing, nutritional supplements, and some savory recipes.
How to Use: Often found in powdered form and added to recipes.
Recipe Ideas:
Homemade Beer
Savory Cheese Crackers
Nutritional Smoothies
6. Nutritional Yeast
Nutritional yeast is deactivated yeast with a nutty, cheesy flavor, often used in vegan cooking.
Best Used For: Vegan cheese substitutes, seasonings, and soups.
How to Use: Sprinkled on food or mixed into sauces.
Recipe Ideas:
Vegan Mac and Cheese
Cheesy Popcorn Seasoning
Creamy Vegan Alfredo Sauce
Hints and Tips for Yeast Success
Storing Yeast
Dry Yeast (Active and Instant): Store in a cool, dry place or refrigerate after opening. It can also be frozen for long-term storage.
Fresh Yeast: Keep refrigerated and use within a few weeks. (or freeze in useable sized pieces and add straight to the Thermomix as directed in recipes.)
Sourdough Starter: Store in the fridge and feed regularly to maintain its strength.
Getting the Most Out of Your Yeast
Check Expiration Dates – Expired yeast may not activate properly.
Use the Right Temperature – Water that’s too hot can kill yeast, while cold water may not activate it. We recommend warming it with the liquid used in the recipe 1 min/37°C/speed 1, then proceeding with recipe.
Feed Sourdough Starter Regularly – A healthy starter leads to better fermentation and flavour.
Allow Proper Rising Time – Rushing fermentation can affect texture and taste.
Store Dough Properly – If you’re making dough ahead, refrigerate it to slow fermentation.
Conclusion
Whether you’re making a simple loaf of bread or a complex sourdough creation, understanding yeast and its varieties ensures the best results. By selecting the right type of yeast, using it correctly, and following best practices, you can create delicious, beautifully textured baked goods every time. Happy baking!
