I am onboard my yacht right now, and the idea of water rat does not curry any favour with me. )))
I have other, more interesting ingredients, and frankly, I think the local mussels would be healthier.
I enjoyed the soups I had in Yekaterinburg and in Belarus. Particularly I liked соляна and would like to find the recipe one day.
I'm not a fan of curry. I have never understood the idea of adding hot spice to food, whether curry or chiles, but then again I love freshly cracked black pepper on my spuds and tomatoes. Not on water rat though.
