Yeast is a living, breathing organism that has the power to turn a bowl of flour, water, and salt into a flavorful, gorgeous loaf of homemade bread, It can be used to make pretty much any baked good that requires rising. But baking with yeast is a bit more complicated than whipping up a quick bread or a batch of muffins. Before you roll up your sleeves and break out your measuring cups, it's important to understand how yeast works, how to tell if it has gone bad (the expiration date, for instance, isn't always spot on), and most importantly, active dry yeast vs. instant yeast.
20 Bakery-Worthy Bread Recipes You Can Make at Home
Yeast is the ingredient that makes dough rise and strengthens the glutens. A leavening agent, and a single-cell fungus, yeast eats the sugars in flour, then releases carbon dioxide. If you've kneaded your dough the right way (using a push-pull technique rendering it smooth and elastic, but not tough), you'll combine the protein from the flours, forming the dough's gluten structure.
There are two main types of yeast that you'll find in the grocery store—active dry yeast and instant rise yeast (sometimes labeled as quick-rise yeast, fast-acting yeast, rapid-rise yeast, or even bread machine yeast). Active dry yeast is used in the majority of recipes.
Active Dry Yeast vs. Instant Dry Yeast
Active dry yeast needs to be dissolved in warm water to be activated—a process called proofing—before it can be added to your dry baking ingredients. Instant dry yeast particles are smaller, and therefore do not need to be proofed before being added to dry ingredients. Instant yeast also releases more carbon dioxide than its counterpart, prompting a bigger rise in baked goods.
How to Activate Yeast
To use active dry yeast:
Dissolve one packet of yeast and 1 teaspoon of sugar in 1/4 cup of warm water (approximately 110 degrees Fahrenheit).
Using a fork, spoon, or whisk, combine the ingredients.
Once the yeast blooms (when it has fully dissolved and starts to bubble), the mixture can be added to the other ingredients. If the mixture doesn't bloom, this is a sign that the yeast is dead.
Substituting One Yeast for Another
You can use active dry yeast in place of instant yeast and vice versa, substituting them 1:1. Active dry yeast is slower to rise than instant yeast, but if your recipe calls for a long rise time (two to three hours), the outcome will be the same. If your recipe has a shorter rise time (such as an hour), add an extra 15 to 20 minutes for the active dry yeast to do its work.
How to Know If Your Yeast Is Alive
Expiration dates for yeast are not always reliable, and yeast often dies long before the date on the package. While instant yeast has a longer shelf life than active dry yeast, there's no way to know if the yeast is still alive when added to a mixture of flour and salt. The benefit of baking with active dry yeast is that by blooming it in water, you can guarantee that it's still alive.
How to Revive Slow-Moving Yeast
When yeast springs into action, bread dough doubles in height in a couple of hours. If yours hasn't risen noticeably in 30 to 45 minutes, try this fix from food stylist and recipe developer Riley Wofford: Fill a pan with boiling water, place it on the lowest rack of your oven, and put your loaf on the rack above it. "Shut the door, but don't turn the oven on," she says. "The yeast will do its thing in a warmer environment."
How to Store Yeast
Yes, you can still use yeast once it's been opened, but it won't last forever. According to Fleischmann's, yeast should be stored unopened in its original packaging in a cool, dark place, such as a pantry or refrigerator. Once a packet is opened, store any remaining yeast in an airtight container in the back of the refrigerator.
Active dry or instant yeast should generally be used within three to four months from when it's opened, but you may also consult the expiration date printed on the package to see if it's still usable. Again, take that date, well, with a grain of salt.
Dry yeast comes in two forms: active and instant. "Active" describes any dry yeast that needs to be activated prior to use, while "instant dry yeast" describes any dry yeast that's ready for use the instant you open the package.
Active dry yeast and instant yeast both help leaven bread and provide an airy, light texture, but they do so in slightly different ways and there's one major difference in how you use them: Active dry yeast needs to be dissolved in water before using, while instant yeast can be mixed right into dry ingredients.
Can I use active dry and instant yeasts interchangeably? Yes, they can be substituted for one another 1:1. We've found that active dry yeast is a little bit slower off the mark than instant, as far as dough rising goes; but in a long (2- to 3-hour) rise, the active dry yeast catches up.
When determining the difference between bread machine yeast vs. active dry yeast, the main distinction is that active dry yeast must be proofed using a warm liquid before use, whereas bread machine yeast can be mixed directly into the bread dough.
Yeast: Active yeast lies dormant and needs a warm liquid to become “activated.” Instant yeast, also known as quick-rise or rapid-rise yeast, does not need to be activated or “bloomed” before using. It's ready to go as-is and simply gets incorporated right into your dry ingredients.
Active Dry Yeast is an ideal yeast to use for artisan breads or no knead breads that require a slower rise time. It's also the preferred type of yeast for those doughs that proof in the refrigerator for extended periods of time.
How to Use Instant Yeast In Baking. Unlike active dry yeast, instant yeast can be added straight into the dry ingredients of a recipe. Though you can proof it beforehand, this is not a required step, and doing so will not impact the activation process.
Additionally we want to tell you some disadvantages of using instant dry yeast that make fresh yeast your best choice: Instant dry yeast is not easily distributed in the dough. The instant dry yeast must be placed at the beginning of kneading.
Active dry yeast quantity should be 1.5 times the quantity of instant yeast to achieve the same dough consistency. Conversely, if you want the active dry yeast to instant yeast conversion, you'll need to divide by 1.5, which is equivalent to multiplying the active dry yeast quantity by ²/₃.
“Yes, absolutely,” Tschenscher says. One reason is that all yeasts do the same things, says Martin Philip, baking ambassador at King Arthur Baking: consuming sugars and starches and then expelling carbon dioxide, which causes the dough to rise, and flavorful byproducts, which causes it to taste good.
Bread machine yeast and rapid-rise yeast are specially formulated for the bread machine and become active more quickly than active dry yeast. You can use active dry yeast in your bread machine, but it should be dissolved in water before being used.
Yeast is a living thing, which means that all yeast expires at some point. All yeast has an expiration date, but yeast will expire sooner if not stored properly. Properly stored yeast may last for up to four months beyond the expiration date. Improperly stored yeast may not make it to its expiration date.
Store unopened yeast in a cool, dry place, such as a pantry (or refrigerator). Exposure to oxygen, heat or humidity decreases the activity of the yeast. After opening, store in an airtight container in the back of the refrigerator, away from drafts. Use within three to four months; freezing not recommended.
Active dry and instant yeasts can be substituted for one another at a 1:1 ratio. Active dry yeast will take about 15 to 20 minutes longer to rise than instant yeast. To encourage active dry yeast to start its activity without having to proof, just use very warm water in your dough mixture (120-130°F).
Active dry yeast is slower to rise than instant yeast, but if your recipe calls for a long rise time (two to three hours), the outcome will be the same. If your recipe has a shorter rise time (such as an hour), add an extra 15 to 20 minutes for the active dry yeast to do its work.
One time when you might not want to use instant and active dry yeasts interchangeably is when you're baking bread in a bread machine. Since bread machines use a higher temperature to raise dough, substituting instant for active dry yeast 1:1 may cause bread to over-rise, then collapse.
This can affect the bread by adding a "yeasty" taste if you put too much into the dough. General amounts of yeast are around 1 - 2 % of the flour, by weight. Too much yeast could cause the dough to go flat by releasing gas before the flour is ready to expand.
Combine flour and spring water in a medium bowl; stir well. Cover loosely with a cloth and let sit on a kitchen counter for 2 to 3 days, or until bubbly.
To use and feed your starter; take out the amount needed for your recipe and then replace that amount with equal parts flour and spring water.
No matter the form it's in, any yeast can work well for making pizza dough. It all depends on how much time you want to spend making it, and what kind of flavor you want. For example, sourdough starter will produce a much different-tasking crust than other yeast types.
