Yes, I know, I know. But I love these baby cabbages, especially after a few frosts. They become a delicacy then at my house. I plant a summer crop for market, but for pure eating pleasure I grow for winter. Nothing I know of that grows above ground can shake off the cold like Brussels sprouts.
I grow them much the same as broccoli in terms of spacing and rich soil. Harvesting begins about 90 days after planting out. Pick from the bottom up before the little heads loosten and start to turn yellow. Flavor is gone at that point. Just break off the leaf below the sprout and pull the sprout off the stalk. Upper sprouts will continue to grow in the leaf axils.
You can freeze them, but why bother when you can pick them for so long. Let Mother freeze them. About the only recipe I know of is to soak for 15 minutes in salted water to drive out any bug larvae, then steam or boil until fork tender. Serve with butter, salt and pepper, maybe some sauteed mushrooms. If you have another good recipe, just hit the comment box, and pass it on.
Oh, and never overcook these things, or any brassicas. It kills their nutrient value and flavor. In the case of sprouts, braise them (covered pot, a little water) so they keep their bright green color. If cooked until they darken, they’re compost.
