Beetroot soup served chilled or cold is delicious during summer for a cooling tummy and also yummy to enjoy this one quick to make recipe.
This soup is on a bit sweeter side because of the beetroots, even if you seasoned more with peppercorns it really doesn't help much, I would just say, have it as it is, with a tolerable seasoning and enjoy it as it is.
If you don't find Kaffir lime leaves you can substitute with one tbsp of lemon juice or just omit it from the recipe
