The crop was bountiful! (It's a small tree and I think it has done rather well). More to the point, it was ripe for the picking.
So time to turn them into something more interesting. All the recipes I found involved equal parts of cumquats and sugar (measured ever so accurately)
And then top up with suitable brandy....
So now we play the waiting game.
Six months according to the recipes. SIX MONTHS!
