No vegetable divides a Christmas table like the Brussels sprout, and no vegetable has a better excuse for being there. The sprout is not on your plate by accident, or even really by choice — it is on your plate because of the calendar.
The right vegetable at the right time
Sprouts reached Britain in the late eighteenth century and became a winter staple in the nineteenth, helped by Victorian tastes for boiled vegetables and by one unbeatable practical fact: sprouts thrive in a British winter. December falls in the middle of their natural season, so when the biggest meal of the year came around, the sprout was the fresh green vegetable actually available. Tradition, as so often, started as logistics.
Frost makes them sweeter — genuinely
The best fact in the sprout’s favour is chemical. Exposure to frost triggers the plant to convert starches into sugars — a survival mechanism against freezing — which makes frosted sprouts measurably sweeter and less bitter. A sprout picked after a cold snap is a different vegetable from one grown soft. If your childhood memory of sprouts is grim, the odds are the problem was the boiling, not the sprout: the sulphurous reputation comes almost entirely from overcooking.

Why they survive the annual complaining
The sprout endures for the same reason the ugly jumper does: the grumbling is part of the ritual. A vegetable everyone merely tolerated would have quietly vanished decades ago; the sprout is argued about, defended, roasted with chestnuts by one aunt and boiled into surrender by another, and that argument is now itself a Christmas tradition. Nobody writes think-pieces about the carrot.
Green on the plate, green on the jumper
The sprout-green end of the knitwear catalogue, for the vegetable’s defenders — and the gingerbread option for everyone who would rather think about pudding.
