I want to make a jelly for 6-8 guests as part of an afternoon tea party. I am looking for a low-sugar recipe with fresh whole fruit (or maybe juice) but sans alcohol (because of DCs). I was planning to use gelatine but the recipes I am looking at quote different amounts of gelatine (from 2 to 5 leaves) and I am a bit confused about the quantity to use. The only gelatine I can buy locally is Dr Oetker which comes in hard shiny sheets.
I was planning to serve fairly small portions - would a pint jelly mould be enough for 6-8? Maybe with a spoonful of vanilla creamy custard ?
