Yes you do cook lasagna before freezing it.
Two or more years of extensive training and on-site experience is required before you can get a certification to be an ultrasound technician or MRI technician.
Blanch broccoli for 3 minutes (or blanch with steam for 5 minutes) before freezing. Freeze in small amounts is better that freezing in a big lump.
yes. if you cook them freezing then ur gonna have some messed up scallops...if had scallops before and their good but my dad (stepfather, can't believe i said that!) cooked them before freezing so...yeah do that!...and yes cook them BEFORE frozen.
The mass of ice after freezing will be the same as the mass before freezing. The volume however, will be greater as ice than it was as liquid water.
