Red Grape Olive Oil Cake FAQ
Do I need to cut the grapes?
If the grapes are large, you can halve them. Small seedless grapes can be used whole.
What kind of olive oil is best?
A mild or light-tasting olive oil works best so the flavor stays balanced with the grapes and lemon.
Can I substitute yogurt for sour cream?
Yes—plain yogurt is a good substitute in the same amount.
How should I store this cake?
Store covered at room temperature for 1–2 days, or refrigerate for longer freshness.
