Just wanted to apologise for not accepting your kind invitation to join this thread to share recipes right away. Unfortunately it all gets a bit complicated when you start talking about measures and products that are not familiar here in the UK. I'm afraid, if things aren't simple or I'm not familiar with them, I get turned off easily....
I understand the concept of using cups to measure and it is a great idea but it really only works with powders or very small aggregates surely??.....For instance, how do you actively measure a cup of rhubarb or strawberries unless you specify the size of chunks it is cut into? Bigger chunks will mean less rhubarb per cup. And we don't have a "cup" as a measure here so I'm kind of lost before we even start as to how much that actually is (volume wise), let alone being sure what Jello is.... I'm guessing it is jelly made with gelatine?
Here in the UK we use scales to weigh most ingredients and then it might be lbs and oz and teaspns etc, pints and gallons if you are my age.... or .... wait for it.... grams and kg, mls and litres by law (thanks Europe!!) to buy ingredients or measure things if you are younger, so things are complicated enough here with recipes and measures without trying to translate recipes to a different system, much as some of them sound interesting.
I've never used pectin before although you can buy it here.... I'm just an old fashioned fruit and sugar woman for jam and throw in some lemon juice and an apple if it isn't good fruit for setting.
Sooooo, you will have to excuse me for not participating at the moment and hope you will understand why I might struggle to get my head round it all!
Funny how our respective nations have so much in common, but other things are so different!
