Spring Lima Bean Soup with Crispy Bacon

Cook bacon in a large pot over medium heat until browned and crisp, about 5 minutes. Use a slotted spoon to transfer to a paper-towel-lined plate.

Drain off all but 1 tablespoon bacon fat. Add oil, onions and celery and cook over medium heat, stirring occasionally, until soft, about 5 minutes. Add garlic and cook, stirring frequently, for 30 seconds. Add water, potatoes, salt and pepper. Bring to a boil. Reduce heat to a simmer, cover and cook until the potatoes are tender, 8 to 10 minutes.

Add lima beans and peas. Return to a boil over high heat and cook, uncovered, for 3 minutes. Remove from heat. Stir in tarragon, parsley and vinegar. Serve topped with bacon and a drizzle of oil, if desired.
