Did you just link JF to Tesco?
I die! Lolol
I did, hehehe ,. and I did it deliberately 
Hah! Rudeness! But I don't care. I got a £14.75 refund from them, and
I have the Coke! I froze the short-dated tortillas, and I guess we'll eat pierogis tonight for dinner. I still got my monies.

But back on topic... I didn't know ambrosia pots were a firmer custard for eating. I thought all the prepared stuff was the pourable kind. I can't think of any reason why it wouldn't work. Just add cocoa powder for the chocolate part.
