I'm a huge fan of soups. I especially like mushroom soups. Portobello, yellowfoot, chanterelle, shiitake. Why favourite is perhaps the false morel.
I like vegetable soups too. Especially pureed ones. I've pretty much perfected the following recipe:
500g sunchoke
500g potato
500g carrot
500g onion
2l of water
butter
salt
pepper
Boil all in a large pot. When everything is soft, take off the burner and use a hand blender to puree it up. Add heavy cream. Cheap and nutritious.
Aside from that I'm also a huge fan of salmon soup. Disregard everything I just said, salmon soup is definitely my favourite. Potatoes, onions, carrots, leek, butter, cream, salmon. All in big chunks. Add salt and pepper.
Spinach soup is also delicious, especially with boiled eggs. You can add nettle too for fiber and flavor.
When I eat out I really enjoy Pho soup with pork belly or chicken.
