How many calories are in black truffle?
Truffle is "the diamond of the kitchen" 💎 A fungus that grows underground next to tree roots, found with trained dogs. There are 75 calories per 100 g, but since it is shaved very thinly over the dish (about 10 g), a portion has only about 8 calories. Expensive in price, light in calories 😄
Does truffle raise blood sugar?
No. Its available carbohydrate is low (about 2 g per 100 g), and it contains fibre, so the glycemic index does not apply. But watch the dish underneath: creamy pasta and risotto are what raise blood sugar and calories.
Truffle or Arabian desert truffle (faqaa)?
Many people confuse them:
- The Arabian desert truffle (faqaa or kamaa) comes up in the desert after the winter rains; it is larger, milder in taste, and cooked as a full dish.
- The European truffle (black or white) has a very strong aroma and is eaten shaved like a seasoning over food.
- Both are fungi that grow underground, but from different families.
Watch out for "truffle oil"
Many truffle oils in the supermarket contain no real truffle, only artificial flavouring. Read the ingredients: if it says "aroma" or "flavour", it does not come from the truffle itself.
How to eat it smartly
- Shaved over eggs or roasted vegetables, instead of creamy pasta.
- A small amount is enough, because the aroma is strong.
