Quite frankly this sounds a bit weird – even for the 70s. It’s a strange combination of a prawn cocktail and grapefruit. I used to make a grapefruit appetiser by halving a grapefruit, segmenting it, pouring in sweet sherry, sprinkling on brown sugar and then grilling the lot – it tasted quite good and was quick and easy to make. It was also pretty cheap (a definite consideration back then). I also used to make prawn cocktails, but only for very special dinners as they stretched the budget quite a bit, but I never combined the two and I don’t think I’ll start now.
I was surprised to find this cutting amongst Mum’s collection as I didn’t realise she had the recipe. It was a starter I made a lot when I first got married. I wasn’t much of cook then and this could be prepared beforehand and was easy to make. It tasted quite good and always seemed to be enjoyed, but it shows how much tastes have changes as I don’t think I’d serve it up to anyone these days.
