What is instant yeast?
Instant yeast is another type of dry yeast that was introduced after active dry yeast in the 1970s. It is made using a similar process as active dry yeast, although is dried more quickly. As you can see, this yeast is also milled into finer particles. Because of this, it dissolves faster and activates quickly. But unlike active dry yeast, instant yeast doesn't have to be proofed first; it can be mixed straight into the dry ingredients with the same result. This yeast also gives you two separate rises and it can be used interchangeably with active dry yeast.
Why we add the sugar to active yeast?
