Everyone should know how to make custard, especially with all those festive desserts you can use it for!

Traditional egg vanilla custard is an essential ingredient for all great British pies and puddings. This low-carb version is just as creamy and delicious but with none of the sugar and starches.

The key to the perfect texture is tempering which will ensure that the custard is smooth and creamy. Don't skip this step, you don't want your custard to curdle.

This foolproof keto custard is the perfect filling for pies and trifles, or you can simply serve it spooned over crumbles or fresh berries.

Now for the pie crust, I've got plenty of different options you may like:

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.

This worked brilliantly for Martina's English trifle and it was so delicious and so simple! I used the smaller amount of gelatine and halved the recipe, and it set just right for me for the trifle. The only thing that puzzled me was that despite covering the custard with cling wrap (with it touching the surface of the custard) so that it didn't form a skin, it ended up forming one anyway, which I eventually stirred in the next day. It did make the custard a bit lumpy but it didn't matter for the trifle at all. Just wanted to mention it here in case I did something wrong? Thank you Martina! Another great recipe 😊

Thank you SO much for all the lovely feedback! We are making the trifle every Christmas! It's a big dessert so we only make it when we know there will be enough people to eat it 😊 I am really surprised about the skin on the custard, this should not happen. I suppose if it did, the only thing to make it smooth would be to blend it again. I'm glad you enjoyed it anyway!

Hi I have made your custard recipe however unfortunately I can’t get it to thicken and set properly. I have added more gelatine and still isn’t setting. Any suggestions would be grateful please!! ☺️

Hi Nicky, I'm sorry for the delayed response! I'm not sure why it didn't thicken but there are a few ways to thicken it:
- Add a teaspoon more gelatine dissolved in a small amount of hot water and beat in while using an electric mixer.
- By using more egg yolks (maybe they were smaller?) You can't go wrong by adding 2 more yolks.
- Arrowroot powder can help thicken the custard but will add extra carbs (about 9 g net carbs per tablespoon). In this case you'd need to add it while still warm and sift it in. If you get any clumps then use a stick blender to process until smooth.
I hope this helps!

Thanks for the recipe. I will definitely be going to give it a try. I have tried a custard recipe from iahas.com, which was delicious. They have some great recipes that are all-natural and very easy to make. You can check them out.
