A strawberry allergy is not the only thing to worry about with strawberries. Besides the Fra a1 allergen, the strawberry also makes chemicals called oxalates and salicylates .
The minimal alcohol product burns off during the baking process, and the yeast dies also with the heat. The ideal temperature for yeast growth is 100 to 115 degrees F., but for leavening purposes, the ideal temperature is 80 to 95 degrees F. If the yeast grows too quickly, it will produce large bubble pockets in the end product. Yeast begins to die at 120 degrees F. So, it is important to let your yeast dough rise in a spot where the temperature is regulated. One-half an ounce of yeast will raise 4 cups of flour in about 1-1/2 to 2 hours, under ideal conditions. You should also proof your yeast to be sure it is viable before using in a recipe.
Feed your fresh yeast. Yeast, similar to when a human or animal is fed, responds to the consumption of the food and water. Activate fresh yeast by mixing it with the warm water called for in the recipe and, if applicable, the sugar. The water must be at the perfect temperature between 90 and 100 degrees Fahrenheit (32 to 38 degrees Celsius). If the water is cooler, the yeast will not activate. If the water is hotter, the yeast will be killed. Add the warm water to the yeast in your bowl. Stir the yeast and water mixture thoroughly. Stir until the yeast is dissolved completely.
