For the hazelnut oil, place the hazelnuts on a baking tray and bake in the oven at 160 °C for 15 minutes.
Empty the vegetable oil into a pot and put the hazelnuts in. Heat briefly.
Let the hazelnuts cool in the oil, then put the oil and nuts in a sealable container.
Leave to infuse for 3 weeks, tightly closed, in a dark and cold place.
Then empty the oil through a sieve and pour into a decorative, carefully cleaned bottle.
Stored in the refrigerator, the hazelnut oil will keep for about 3 months.
Preparation Tip:
Hazelnut oil goes well with any salad as a dressing, with desserts and cakes, with short roasted meat such as veal or with any freshwater fish.
