I’m not sure why some of the blueberries sank but the majority floated; it didn’t matter at all, if anything it added a slight curiosity to the dessert. A large serving spoon is your friend when serving this up lest it wobble its way off a smaller spoon onto the table or floor. I made it in a bowl as I thought it looked pretty but you could divide it between glasses or jars as I did for my blackberry and perry jelly previously. I love the delicate colour of the elderflower jelly broken up with the little blueberries. The flavours worked really nicely together too; a light bowl of summer perfect for the warm evenings.
