Believe it or not, but tofu is a food storage food. I freeze it!
First, some basic explanations on tofu, since most people aren't very familiar with it.
What is tofu?
Tofu is soybeans processed in a fashion similar to cheese.
Where can I buy tofu?
Tofu can be found in your local grocery store in the refrigerated section of the produce department. It is next to eggroll and wonton wrappers.
Why should I eat tofu?
It's healthy, and a great source of protein.
What types of tofu are there?
Silken-can be used in smoothies and as a substitute for cream cheese in cheesecake. I never buy this kind.
Firm and extra firm-This is the kind I buy. I marinade it, then fry it.
More about tofu
Tofu is packed in water, and acts as a sponge. So, if you plan to marinade it, you want to get as much water out of it first, so that it can then soak in the marinade. You can get water out of it by using towels, paper towels, or smashing it between two plates with some heavy cans on top.
Just like every other food, I try to buy tofu when it is on sale, and then buy more than one package. Within the past few months I have seen tofu discounted for quick sale, and Buy One Get One Free. Great times to stock up. Tofu firms when it is frozen. To freeze tofu, I just take it out of its original package, squeeze some water out of it (see above), then put it in a marked freezer bag.
Cooking frozen tofu
I make up my marinade (I like teriyaki) in a bowl, then put the frozen tofu right in the bowl with it, and store it in the fridge with a lid. When the tofu is defrosted enough to cut, I cut the tofu in cubes (about 1 inch), then put it back in the marinade. Store in the fridge until the tofu has taken in the marinade (about a day). Then I cook the tofu (without the marinade) in a fry pan with a little oil, stirring minimally. Then I add the marinade, and take out the tofu (you can use the same bowl through this whole process, since you're using tofu, not meat), and let the marinade simmer. This thickens and enhances the flavor of the sauce.
