Well, that could mean a lot... In our speech, it can mean the sky is laden with grey clouds and mist, and you don't see a thing. Pea soup, thus. Or it can mean the future is not clear - like today, without doubt, in the United States.
But right now I mean the soup only. While listening to the latest news on the radio - all the reactions and comments on Trump's victory - we've made pea soup. The old-fashioned way, like our grandma did.
This means you let split peas soak for a night in water. This will make your soup better to digest. For the rest, you also need 2-3 leeks, some onions and a few twigs of celery. Start by putting a big pot on the fire and melt some butter (real one is the best). Then add the onion, leek and celery. Let stew for a while and then add the peas. Later on you add about 3 liter of water. Wait until the water boils and then drop some stock cubes (6, and preferably of beef). Once they are dissolved, you let the pot boil for another half hour to 3/4 of an hour. Mix, and your soup is ready.
To make finer, you can also add some bacon and cream.
