Can I put frozen yeast in baking, if their expiration date has long expired?

The shelf life of products is not taken into account by many people for a while. Before the first poisoning, to be exact. That's exactly what I had. I am now carefully checking the date of manufacture of each product, trying to protect myself and my family from this kind of trouble. My experience in this field is already decent, but the old yeast is still confusing...

The opinion of the housewives about old yeast is divided. Moreover, many people avoid even using fresh products. Like, this is an artificial product and it is better to bake bread in the old-fashioned way, without any yeast there. It's hard to tell truth from fiction.



Those who still can not live without baking on yeast, have to twist, coming up with different ways to store this ingredient. And beginners sometimes do not even know what yeast is at all. Let me refresh your memory!



Types of yeast

1. Fresh cubes
   Most often, bakers prefer this option for baking bread. They are quite wet (as much as 70%), and therefore provide fermentation. Such yeast should be stored at a temperature slightly below 10 degrees no longer than 6 weeks, but at room temperature they will not last a day. 848000
   
   
   
   Pressed yeast does not like the lack of air, and therefore do not need to store them in sealed packages. Remember that when pressing the bars should crumble, not wrinkle. Only such yeast will be of quality.
   
   
   
   
   
   I've heard more than once that I can. saltKeep them out of the refrigerator for a little longer. Have you tried that?
   
   
2. In granules This option is drier and acts slightly worse than fresh yeast. Their storage rules are almost the same. The advantage of the product is that it does not need to be diluted with water. You can immediately add to the flour, which will ensure an even distribution.
   
   
   
   
   
   
3. Dry In such yeast 6% moisture, and they need half as much. Store them is very simple, it does not need low temperatures, and the shelf life is about two years. But do not forget that their use is significantly different from the previous options.
   
   
   
   
   
   In order for dry yeast to work, you need to gently pour them on the surface of the water and let them dissolve. After 15 minutes, they can be mixed and used.
   
   
4. Fast acting Progress is not standing still. Thanks to him, we have the opportunity to buy a very powerful type of yeast. They can be added directly to the dough, previously mixed with a spoon-second flour.
   
   
   
   
   
   

I still prefer the first option, because most of the recipes that I got from my grandmother, it is fresh yeast. But I have often forgotten that there was a pack in my freezer. What do we do with them now? They say the test just needs to be done. bit moreIf you cook it with old yeast. Tell me if you used expired frozen yeast and if the baking was successful!
