Source: This pea soup recipe was found in Ein New Kochbuch by Marx Rumpolt, a 16th century collection of German recipes
Original Recipe:
Erbeßsuppen mit klein gehackten Zwibeln/ die geschweißt seyn/ pfeffers vnd gelbs/ so ist es auch gut.
Translation:
Peas soup with small chopped onions / which are sweated/ pepper and saffron/ so it is also good.
My Interpretation:
Mince onion. Sautee onion in bottom of stock pot with oil until translucent. Then add broth and water, saffron, pepper, salt, and peas. Bring to boil. Simmer for 2 hours until peas are soft. Then use an immersion blender to the soup to make it creamy. Then serve.
Notes:
The original recipe does not specify any particular broth, I choose a vegetable broth to give make this dish vegetarian for feasts.
The original recipe does not specify if fresh or dried (split) peas are used, I choose to use split peas to show how this dish can be made with preserved foods.
I like to caramelize the onions to bring a little smoky flavor to the soup.
