Food extracts can be full of unwanted sugar and other additives such as propylene glycol. The good news is that it's very easy to make your own.

This recipe was adapted from PurpleFoodie. Instead of sugar, I used Erythritol, a healthy low-carb sweetener.

Roasting hazelnuts and infusing them in alcohol really works! Although the original recipe calls for 3-4 weeks, you will be surprised how much of amazing flavour you can get in just 2 weeks!

Tip for an occasional treat: Add some heavy whipping cream to get creamy hazelnut liqueur!

Instructions

  1. Preheat the oven to 175 °C/ 350 °F. Toast the hazelnuts for 8-10 minutes. Homemade Hazelnut Extract (Hazelnut Liqueur)
  2. Cut the vanilla beans lenghtwise and scrape the seeds out. While the hazelnuts are still hot, transfer them into a glass jar and top with vanilla seeds. Add vodka and the vanilla beans to the jar. Homemade Hazelnut Extract (Hazelnut Liqueur)
  3. Infuse for 2-4 weeks. The longer you leave it, the more intense the flavour will be. After 2-4 weeks, remove the vanilla beans and drain the hazelnuts. Reserve the extract. Homemade Hazelnut Extract (Hazelnut Liqueur)
  4. Transfer the hazelnuts into a blender. Pulse 3-4 times until roughly chopped and place them into a pot. Add water and bring to boil for a minute. Remove from the heat and press the hazelnuts through a sieve, to remove any remaining fluids. Mix it with the rest of the extract. Homemade Hazelnut Extract (Hazelnut Liqueur)
  5. Pour the extract through a sieve (ideally also cheesecloth) to remove any pieces left. You can discard the chopped hazelnuts.
    Note: If you prefer the extract clear, you can use a cheesecloth on top of the sieve to remove even the smallest pieces. Don't push it through, just let it drip slowly.

  6. Add low-carb sweetener of choice (if any) and mix in well.
    Note: If you are using Erythritol, don't forget to powder it first. Erythritol does not dissolve well unless heated or powdered. Homemade Hazelnut Extract (Hazelnut Liqueur)
  7. Pour the hazelnut extract into a glass jar that has been sterilized in hot water and seal well. Homemade Hazelnut Extract (Hazelnut Liqueur)

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.

HI Martina
This sounds great. I would love to try it out. Thanks for sharing.

Seems as if more flavor would be extracted if the nuts & beans were chopped in blender before adding the alcohol.

I think that it won't make much difference (keeping them in alcohol for 2-4 weeks should be enough) but you can give it a try and let me know 😊

I made a batch 4 weeks ago and tried it in low-carb pancakes today. I also used hazelnut flour in my pancakes and this extract gives it a nice flavour boost!
