This is an amazing, yummy and simple cake to make! I have surprised friends and family with this and NO ONE has guessed it has green tomatoes in it :-)
The changes I made were
1) use half the amount of sugar
2) replaced butter with oil
3) I don't use walnuts due to allergies, so sprinkled the top of the cake with pumpkin seeds - nice and crunchy.
4) I mixed the tomatoes, oil, sugar, eggs and raisins together, then folded in the sifted the dry ingredients, much easier
5) And preparing the tomatoes, I blended them in the food processor then drained them in a colander, then squeezed any excess liquid out (froze what I didn't use)
