This time I used frozen pie sheets, but you can also make a quiche with homemade pie crust. Making holes in the bottom and sides will help prevent the pie crust from lifting, but it may puff up when the weight is removed and baked again. In this case, do not panic and crush the bottom of the baked dough a little.
By boiling the bacon once, you can drain off the excess fat and salt. It is difficult to adjust the salt level in dishes that use cream or eggs. Especially in dishes like this one where a lot of cheese is added later, too much can make the dish seem quite salty, so use a little less salt when frying the vegetables.
Gruyere cheese melts at a lower temperature than Parmesan cheese, so it is best to add Gruyere and Parmesan cheese in that order for the best-baked surface.
Rehydrating dried Shiitake with cold water gets rid of bad odors and brings out more sweetness and flavor.
