Spinach revelation

I try to cook with spinach regularly: being vegetarian, iron deficiency is an issue for me, and my body seems to absorb iron from spinach better than any other food. I have for years (my entire grocery shopping career) bought frozen spinach as a block.

At my last grocery shopping trip, the store was out of the frozen spinach blocks. Nothing, not even way back on the shelf where only my husband can reach. Searching through the frozen vegetables section, I find frozen spinach in a bag. A bag of frozen spinach? It struck me as so odd. But I got two.

I can't believe I haven't discovered this before: I can use just half the bag without the assistance of a bread knife. I can stir the pieces of spinach into my dish without having to wait for the entire mass to melt. The pieces melt faster than a block does, too! Why would anyone buy a frozen block when bagged pieces are available?

There must be some advantage to the blocks. But as for me, I am a convert to the way of the bag.
