Turn your classic lemon curd into a delicious tropical treat with sweet-tart passion fruit. It's the perfect low-carb filling for summer pies. I used my classic Low-Carb Lemon Curd and swapped passion fruit juice for the more common lemon juice. It's so incredibly delicious, just the perfect flavor for summer!

Instead of sugar we are using a healthy low-carb alternative. Allulose would be your best option as it would make the curd super smooth. Erythritol-based sweeteners are fine but there might be some sweetener crystals once the curd is chilled.

Is Passion Fruit Keto?

Although passion fruit is a tropical fruit which is relatively high in carbs, it can be included in a well formulated low-carb and keto diet, as long as you use small amounts. The good thing about passion fruit is that you don't need a lot of it to bring amazing flavor!

You may have heard from other bloggers that certain "foods are not keto" which is a myth we've debunked here. If anyone ever tells you that, remember that lower carb is not always better, and zero-carb doesn't necessarily mean it's a healthier approach for you.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.
