My most successful cheese yet

This is now the third or fourth time I have tried to make cheese. It definitely was not a success, even though it was my most successful so far. I think my frozen cultures lost a lot of their potency when the power was out for week (plus they are pretty old--they are supposed to be used within 6-9 months of purchase and mine are about 18 months old). In any case, after adding all of the different kinds of cultures I have and letting the milk ripen 2 times as long as it called for, I became too impatient to try anything else and proceeded with the recipe.

This feta turned out solid and crumbly (much better than my last feta which was more like cream cheese).
