Yes,
Smaller harvested bulbs will be a disappointment.
One crappy onion harvest, I took the smaller bulbs and pickled them.
I started with a standard lacto-fermentation then I rinsed them and finished them off with a hot vinegar / sugar pickle.
Onion / garlic lovers appreciated them and, those who don’t enjoy onions complained about how the eaters smelted after their snack… So, I considered that part of the harvest a success!
