Active dry yeast is a commercially available form of yeast, commonly used to leaven bread and other baked goods. Typically sold in small granules or packets, it consists of live yeast cells that have been dehydrated to extend their shelf life. This versatile and crucial ingredient aids in the fermentation of dough, producing carbon dioxide gas which makes the dough rise, resulting in a light and fluffy texture.
To use active dry yeast, it must first be rehydrated and activated, usually by combining it with warm water and a small amount of sugar. Once foamy and bubbling, it's ready to be incorporated into your recipe. This essential ingredient is highly regarded by home cooks and bakers alike for its consistent and reliable results in various baked goods such as bread, rolls, pizza dough, and pastries.
Active dry yeast can sometimes be tricky to use right, and it’s not uncommon for novice bakers to have a few hiccups when working with it for the first time. The most common issues that people run into usually involve either not properly proving the yeast, or using water that is too hot or too cold. Underproofed yeast will make your dough heavy and dense, while water that's too hot can kill the yeast and too cold won't activate it. To get the most out of your yeast, always proof it in warm water (around 110-115 degrees Fahrenheit) with a spoonful of sugar. The sugar acts as food for the yeast, helping it to activate more quickly.
Another important tip is to be patient. Rising times are just suggestions and can vary based on the temperature of your ingredients and the climate in your kitchen. It's better to wait longer and allow your dough to fully rise, rather than rushing the process and ending up with dough that hasn't risen enough.
Lastly, did you know yeast can be used for more than just baking? It's a great ingredient for homemade fermentations. You can use it to make your own wine, beer, or even sourdough starter!

Expiration & Storage Tips
When does active dry yeast expire?
Unopened, active dry yeast should last until the date printed on its package, typically around 2 years from production. Once opened, it'll maintain its leavening power for about 4-6 months if stored properly, even after the package 'best-by' date. Although you can freeze active dry yeast to extend its shelf life up to a year, frequent defrosting can kill the yeast cells, so only freeze as per your requirement.
How do you tell if active dry yeast is bad?
To check if active dry yeast is still good, you can do a 'proofing' test; dissolve a teaspoon of sugar in a half cup of warm (110-115°F, 43-46℃) water, add a packet (2 1/4 teaspoons) of yeast, and wait 10 minutes. If the mixture bubbles and develops a yeasty aroma, the yeast is still active. If not, it's time to replace it. Also, if you notice the colour becoming darker or it develops a stronger smell, these are signs it has gone bad.
Tips for storing active dry yeast to extend shelf life
• Keep the yeast in a cool, dry place such as a pantry
• After opening, storing it in an airtight container in the refrigerator can extend its life
• If you live in a hot climate, keep the yeast in the refrigerator, even if unopened
• If you choose to freeze it, avoid frequent defrosting. When you need some, measure out the required amount and let it reach room temperature before using it to make sure it's still active, then return the rest to the freezer quickly
