This recipe was from an old member on here, cg74 . . . . I've tried it a few times and been successful, but I add a few drops of cheese flavouring . . .
"
The best cheese paste mix I've found goes:
250 grams frozen shortcrust pastry.
250 grams of blue cheese (my preferred choice being stilton)
100 grams extra mature cheddar
Freeze ALL the ingredients and grate into a bowl, then either mix quickly by hand or I blitz with a food processor until mixed evenly.
Leave to stand and thaw for a day somewhere warm, during which time excess moisture should evaporate off.
Then knead until an even paste, if still to sticky add corn flour slowly whilst still kneading.
If using in very cold water try mixing in 50-100 grams of soft cheese such as Brie. (if adding Brie I always leave unrefrigerated for about a week to ripen)
Just freeze unused bait in a plastic bag and when making a new mix up try and add a little of the old mix in to aid 'ripening'.
Regards additional flavourings, I'd do so very cautiously, otherwise you'll get an overpowering turnoff.
Though replacing the cornflour with instant custard powder or a little chilli both work well.

I tried to find the Dave slater cheese paste recipe but couldn't find it.
