I’ve been asked if a food processor or blender is necessary to make this cake and the answer is, “yes.” Unfortunately, it would be too difficult to chop the orange as finely as needed by hand. You can see how fine the orange is processed in a photo below, however, an inexpensive food processor works great.

EDITED 7/2022: Daniel Coffey (a reader) left a tip for those of you without food processors in the comments below. Since it might be difficult to find, I’m adding it here:

“I…cut the peel into coarse strips and then finely diced them. I put the chopped bits of orange into the spice grinder in two batches and pulsed the stick blender a few times. I tapped it on the counter top to shake down any remaining coarse bits and gave it about 30 seconds. Scrape out and repeat for the other orange half. You can then put the juice and finely chopped peels in the recipe as normal.”

I highly recommend using a scale for this recipe and if you are deciding cups or weight, ALWAYS weigh!
