I think horseradish can be a bit of a nuisance in the garden.
We have an allotment and go there in the morning weather permitting. We collect whatever is ready, bring it home chop it up, add olive oil and balsamic vinegar. While it is cooking we have our showers, add some garlic bread to the oven, then have a delicious lunch. It is often fennel, beetroot, shallots, tomatoes, garlic, broad beans, butternut squash and anything else to hand.
Asparagus, lightly cooked just after picking is delicious and even when my gc were tiny they ate it like sweets.
