Nestle Sweetened Condensed Milk is of offer at Tesco, 50p a can
Very useful stuff, I like it in fresh coffee (I know Ian, you don't), its good with fresh fruit salad, great in cheesecake etc
If like me you use refillable 'squeeze tubes' it good for camping and will stay fresh several days in the tubes.
I picked up 34 cans last week and daughter just got me 22; I'll go Friday for more. Good for long term storage and lasts longer in the can than evaporated milk. Ideal for 'preppers' and campers alike.
