This undetectably vegan Spicy Miso Mayonnaise is easy to make, bursting with umami flavour, and irresistibly creamy.
It all starts with some cashews, which are blended until thick, creamy and luxuriously smooth. I mentioned that I’d been experimenting with soaked cashews, which I love for making delicious sweet treats, as well as savoury sauces like this mayonnaise!
I add a dollop of miso for a hit of umami flavour, along with some vinegar for that characteristically mayo-like tang, as well as a good dash of chilli powder for a spicy kick!
You can use Japanese seven-spice powder (known as shichimi) instead of chilli powder if you wish – it’s a blend of chilli, orange peel, black and white sesame seeds, seaweed, ginger and Japanese pepper. You can find it in Asian supermarkets or online.
I’m SO pleased with this sauce: it’s a super delicious, infinitely healthier and unnoticeably cashew-based alternative to traditional mayo! It also happens to be oil-free, which is an added bonus.
This mayonnaise is great as a dip for:
- regular potato fries
- sweet potato fries (see recipe below – I used a mixture of regular orange sweet potatoes, white-fleshed sweet potatoes and purple sweet potatoes)
- any other vegetable fries
It can also be:
- slathered on greens
- tucked inside sandwiches
- spread on burgers
