Between the Naija heat and perennial power issues, I learned which soup type stays fresh when preserved well and which ones don't.
I have liked Egusi soup for as long as I remember. Edikang ikong on the other hand didn’t become a favourite until I was a teenager. According to my mum, I would pick out all the vegetable and fish until there was just a little liquid left of the soup, before I would put a morsel of the meal in my mouth.
If you are trying to figure what common Nigerian soups you can cook in bulk, this list should give you a fair idea of how to plan and prepare your meals.

1. Egusi
Surprise! Egusi soup notoriously goes bad easily, but it can actually be preserved for long periods and still taste good if handled and frozen with care.

2. Banga
Banga tends to last long and can even taste better with time. However, it’s still important to handle it with care and freeze properly though.
