Bittersweet

It’s a few years since I made marmalade. I used to make it every year and developed quite a stockpile and couldn’t eat bread for a while after my last cancer treatment, but the time has finally come. I checked one of the local supermarkets online for Seville oranges before setting off as they aren’t always available. I read the reviews which either said they made excellent marmalade. 5* or very bitter and impossible to eat 1*. I suspect the latter reviewers didn’t understand the concept of Seville Oranges.
