Watermelon gazpacho with Nagabon chilli kick.

Watermelon gazpacho is the absolute summer must-have. With the vibrant sweet watermelon and the fires kick from the nagabon chilli topping. Enjoy the summer freshness with the easy vegan option.
It was a note in the suburbs to check for interest to try out some nagabon chillies that got me started on this watermelon gazpacho. The variety of homegrown chilli that is around my residential area is amazing. Even better is how the community shares the produce. I was happy to exchange the couple of nagabons for a bunch of mint.  The superspicy nagabons needed a gentle soothing partner to be tried with. Watermelon gazpacho has that mellow sweetness that helps not to set your mouth on fire and so here we are.

Prep up for watermelon gazpacho

Watermelon gazpacho is one of the easiest cold soup recipe you can try. Just a couple of ingredients and a giant watermelon makes a good batch of soup prepped and ready for a couple of days.
Watermelon- get a good seedless watermelon for making this soup. This helps when you blend up the soup the fibres can remain and the soup doesn’t become watery. You can choose the red ones or the yellow ones. I tend to quickly go to red the colour that is the most vibrant in them.
Veggies – so this is where you can add variety. Roma tomatoes, a cucumber, red peppers (capsicum) and garlic are a must for a Spanish style cold soup. I prefer to chop up my red onions and not really blend them in. If you prefer a smooth soup like the tomato cold soup we did, add them to the blender along with the other ingredients.
In addition to this, we love a little bit of a bite to the watermelon soup so it is unlike watermelon juice. So finely chop the onion, avocado and nagabon chilli to add to the centre of the bowl when you ladle out the soup. Squeeze a bit of lemon in this mix if you are storing it so the avocado doesn’t darken. to this mix, you can add some fresh sweet corn as well.
Bread- the watermelon and the veggies are all water-laden and the soup can be thin. To avoid this add the soft part of the soup while blending. This thickens and gives a scoopable feel to the soup.
Herbs- I love just a bit of torn mint and added to the bowl. It just adds a bit of freshness to the soup
Vinegar – red wine vinegar tastes the best with gazpacho soups..it adds the acidity that Roma lacks.
Oil- a good salad grade olive oil is the one that rounds sup the flavours in any Spanish dishes. Just a couple of drops on top elevates the flavour.
Spices- other that salt and pepper to flavour, try a pinch of cumin seeds in the blend. That peps the flavour a lot more than just making taste like just watermelon.

Perfect pairing with the watermelon gazpacho.

It pairs well making this soup a filling lunch. If you are taking this up to the beach picnic, pack up some loaded vegemite sandwiches and this soup in a cold pack.

Watermelon gazpacho looks so tempting and love the use of nagaban chilli. I once accidentally put one habanero in my curry and we had to through all of the curry as it was outrageously hot.

Interesting Post Seema. Being a big fan of chillies, I loved reading every bit of it. I recently tasted Bhut Jholokia or Ghost Pepper flavoured honey but could still feel that spice kick hitting the head. You have transformed that wonderful produce so lovingly gifted by the family into something really refreshing. Those chillies look like cute berries but I am sure, the heat kick is top notch!

My capacity to take heat is very limited, thanks to umma never giving us spicy food, so I think I would die with that fiery looking chilli! Hehe… having said that, I love how you explained the whole reaction, the body is such a wonderful machine, isn’t it? Beautiful color of the gazpacho, such a needed soup for the upcoming hot days…
