We did the same with vodka jelly one summer. Luckily I have since found a jelly brain mold last Halloween to distinguish between whose is whose.
This entire thread makes the British contingent look like a bunch of alchies when in reality I hardly drink at all. If 21 units is the recommended level per week I am lucky if I have that in 3 months....just for the record your honour. Don't want everyone thinking I dose my daughter up on vodka jelly to keep her quiet!
