FAQs

Can I use bottled grapefruit juice?

Fresh juice is best for flavor, but bottled juice works in a pinch.

Why did my filling crack?

Overbaking can cause cracks—remove from the oven as soon as the center is set.

How do I get clean slices?

Chill completely before slicing and wipe your knife between cuts.

Can I use a different citrus?

Yes! Try lemon, orange, or a mix of citrus for variety.

What size pan should I use?

An 8×8-inch pan works best for thick bars, but a 9×13-inch pan can be used for thinner bars.

How do I make the bars extra smooth?

Sift the flour and cornstarch before adding to the filling for a lump-free texture.

Can I make these ahead of time?

Yes! They taste even better the next day after chilling.

Do I need to strain the grapefruit juice?

Yes, straining removes pulp for a smooth filling.

How do I make them sweeter?

Use a sweeter variety of grapefruit or add an extra tablespoon of sugar.
