Step-by-step instructions on how to make the traditional Dutch split pea soup called "snert". Unlike the American variety, this is a thick soup full of vegetables and pork. A classic winter dish, it's commonly served with pumpernickel bread and cured, uncooked bacon.
Please note that I am not giving any ratios or amounts. I think all of the ingredients are essential, but, for example, you can add more onions if you like them, use less meat if you prefer and so on.
Step 1: Ingredients
Ingredients: Peas, celery root, celery leaf, potatoes, onions, leeks, carrots, pork chops, bacon, and kielbasa (in lieu of Dutch smoked sausage). Bay leaf, cloves, and pepper to taste.
Step 2: Celery root
The key ingredient to this soup is the root of the celery plant. It imparts a very distinctive flavor.
Step 3: Meats
This soup is chockfull of meats. Specifically: pork. Slab bacon, cut into chunks; a bone-in pork chop (or pork feet, traditionally) and Dutch "rookworst", a smoked sausage. You can substitute one of those vacuum sealed Kielbasas for the rookworst, or better yet, a fresh Kielbasa from your local Polish butcher.
Step 4: Start
Put peas in pan along with the pork and chopped up bacon and some bay leaves and cloves. Bring it to a low boil.
I usually eyeball it, but I think the ratio is around 500g split peas to 1 liter of water. If it gets too thick too soon, just add water.
Step 5: After a couple of minutes
It'll start to foam. Remove the foam with a slotted spoon.
Step 6: Prepare the rest of the ingredients
Peel the potatoes and the celery root, and cut into big chunks. Do the same with the onion, the carrots, and the leeks.
Step 7: Leaf Celery, or celery leaves
If you can find it, use leaf celery ("Zwolse Krul"). Otherwise, get some nice leafy celery stalks and chop up the leaves. You won't need the stalks; save them for a Bloody Mary or something.
Step 8: Add everything to the pan
and bring it to a nice slow boil.
Step 9: No set time.
This can easily take an hour, or more. It doesn't really matter. You'll know when it's near to done when the veggies start to dissolve and the peas are starting to bind the liquid.
