This is a long recipe...sort of fitting, cause if you're crazy enough to make your own perogies it's going to take you a good part of your day! In the mushroom filling, we always use Portobellini mushrooms for a stronger mushroom taste. In any of the fillings you can adjust the quantities to suit your own personal taste. We LOVE garlic so we saw no problem with using 20 cloves in the potato and roasted garlic filling (roasting mellows out the flavor)!
