Instead of blanching cabbage in boiling water to prepare it for stuffing, here are two simpler alternatives that work great. First: try wrapping and freezing the whole head of cabbage. Before using it, let it thaw in the fridge overnight, then separate the leaves. The cabbage will be cool to the touch and easy to handle. It’s ready to stuff.
Or: EllenMM’s fast approach is to microwave the whole head of cabbage for 7 to 8 minutes instead of blanching.
