Platinum Instant Sourdough Overview

Have you ever wished you could make sourdough bread without going through the trouble of keeping and maintaining a sourdough starter? Well, now you can! Red Star Yeast just released their brand new product: Platinum Instant Sourdough Yeast

What is really awesome about this yeast is that it combines the convenience of dried yeast with the flavor of real sourdough. It really is brilliant! 

What is Platinum Instant Sourdough Yeast?

Platinum Instant Sourdough Yeast is a  blend of Red Star’s Platinum Instant Yeast and a real dried sourdough culture. This lends an authentic sourdough flavor to your breads without a finicky starter. 

Platinum yeast is the dried yeast I have used and loved for years. I’ve shown it many times in my yeast bread recipes here, and often use it in my bread baking on Instagram. Platinum yeast is a unique two-in-one blend of instant yeast and natural dough strengtheners for a superior rise, both before and during baking. This means not only will your bread have a real sourdough flavor, but it will surely bake up beautifully as well. 

What is a Sourdough Culture?

A sourdough culture (also called a sourdough starter) is a natural culture of yeasts, as well as bacteria, that is used to leaven bread. A live sourdough culture must be cared for and fed frequently to keep it lively and active. Many bakers find a lot of joy in this process, but others find it to be too finicky and not worth the effort. 

The Platinum Instant Sourdough Yeast contains a real sourdough culture in it. This culture has been dried out and deactivated so it can go right into your bread dough to add its authentic sourdough flavor. 

How to Use Instant Sourdough Yeast

Using the Platinum Instant Sourdough Yeast is extremely simple. All you have to do is substitute 1 full package for a 1/4-ounce packet of dried yeast in any recipe. That’s it! 

The instant sourdough can be used in any recipe that calls for dried yeast, weather it calls for active dry or rapid rise (aka instant or quick rise) yeast. It really works beautifully in any yeast bread recipe, but I especially love using it with my easy no-knead bread and my basic pizza dough

The Package Looks Bigger? Do I use the Whole Thing?

The instant sourdough package is a bigger package than traditional dried yeast. A package of dried yeast contains 7 grams of yeast. The Platinum Instant Sourdough is an 18 gram package. 7 grams of the contents is the dried yeast and the other 11 grams is the dried sourdough culture. 

You do want to use the entire package and it is not advised to use only part of a package. Because it is a blend of the dried yeast and the sourdough culture, you wouldn’t be sure how much actual yeast you were putting in your recipe if you didn’t use the whole package. 

Can I use the Instant Sourdough in Recipes that Call for a Sourdough Starter? 

The instant sourdough is not meant to be used in recipes that call for actual sourdough starter. Recipes that call for actual sourdough starter have different ratios of flour and liquid in them and the timings of the recipes also work differently than with dried yeast. 

Do I need to Let My Dough Rise Overnight?

The sourdough culture in the instant sourdough yeast is not alive so it does not ferment once it is added into the bread dough. The dried yeast is the thing that will be fermenting, so it does not require the long fermentation times that bread made with live sourdough starter does. 

However, anytime you are making bread whether with dried yeast or active sourdough culture, doing a long slow ferment does increase the flavor of the dough. You can choose to put your bread dough in the refrigerator overnight to slow down and prolong the fermentation process. This will extract more flavor from the dried yeast.

Sourdough it Up! 

A few weeks ago I had the privileged of joining Red Star Yeast at the Pizza and Culinary Institute to learn all about their new Instant Sourdough Yeast. I was so excited, because as you probably now by now, I absolutely love sourdough bread! But I totally understand that not everyone is interested in maintaining a starter. This is such a great alternative! 

We had the pleasure of taking a Pizzaiolo Masterclass with Master Istruttore Leo Spizzirri! It was such a wonderful experience. He showed us how to properly stretch pizza dough and how to make the perfect Neopolitan style pizza. Then we got to try our hand at making our own pizza with the Platinum Instant Sourdough Yeast and we competed against each other in the Pizzaoli challenge.
