Romanesco cauliflower (also known as Romanesco broccoli) comes from Italy where it has been grown since the 16th century. It’s still not all that common, but you do see it in a few dishes.
The advantage of Romanesco cauliflower over the regular one, apart from the obvious win in the beauty department, is its lack of the slightly bitter taste the white cauliflower has, which makes it far more popular with children. Instead it is a bit nutty and pleasantly delicate.
Roasted Romanesco cauliflower pesto
If you love pesto this Romanesco pesto sauce will be your best friend! It couldn’t be easier, just roast cauliflower and then blend all pesto ingredients in a food processor.
My only word of advice with homemade sauce is taste it for seasoning and add SALT!! My first try at making my own pesto was not a success. I learned that is because I hugely undersalted it. Yes, it’s that simple.
To make this pesto you will need:
- Olive oil
- Toasted walnuts
- Vegetarian hard cheese (made with vegetal rennet)
- Fresh basil
- Roasted Romanesco cauliflower florets
Once the cauliflower is roasted add the cauliflower, walnuts, cheese and basil to a food processor and run until it is all nice and smooth. Leave the motor running and pour the olive in through the shoot.
The pesto will become lovely and smooth. Give the pesto a taste and add salt, lemon juice and lemon zest to taste. Combine all of the ingredients by running the processor for a few more seconds.
Toss the pesto with cooked spaghetti and you are ready to eat!
