Just been looking at this recipe from James Martin. You have to simmer the oranges in water til soft, let them cool then chop them up and whizz in a food processor (minus pips) with sugar, eggs , almonds etc. He doesnt say you have to remove the peel so I am assuming that as its gone soft it loses its bitterness ? Has anyone made this cake before ?
Even though you blend it in a processor, if you don't like peel in your marmalade you may not like the texture of the cake. I've made it several times and it can have a grainer texture than a normal sponge cake.
Why do people always assume you have a processor. What do I do if I haven't got one? Well, give up and not make the cake I suppose, but I would love to have a go at it and I can't. It's like assuming you have a computer. Not everyone has one. Or even a PS3.
