I get the slices pre packed from aldi there are 4 in a pack for 99p, each slice about an inch thick is 2 1/2 syns. If you have had it out depends how it was cooked it could be more but i dont think 2 1/2 is that bad.for using at home just grill ot with frylight.
Recipe idea for black pudding.
I use two slices of black pud with lots of grilled bacon chopped up in salad then dress with fat free youghart with 1/2 teaspoon of english mustard stired in its yummy.
Hope this has helped x
