Thank goodness fats are no longer considered a toxic substance. I did my nutrition studies during the height of the low fat is healthy years. Just imagine how confused I felt when I ran my own numbers and discovered my daily pattern was based on an unhealthy amount of fat. That was just 20 years ago and as you know things have changed.
My split pea soup depends on fat to bring out the flavor of aromatic vegetables – onion, carrot, and celery. Finely chopped and sweated in lots of olive oil, this mirepoix adds color, hearty flavor, and sweetness to the soup. Without that generous dose of olive oil, the recipe wouldn’t be as delicious.
Salt of course is the other critical component. I learned I use too much fat but I also learned I under salt. Salt is critical to good cooking but if you know your way around the kitchen you know how to squeeze flavor out of all the ingredients so there’s no need to use so much salt.
Recipe writing is not my strength. I do provide proportion but in both metric and common measure and some instruction. But if you’re a beginning cook and need basic instruction or technique, I suggest you check out a website like Simple Recipes or New York Times Recipe Box or one of the reputable collections available via the internet.
Rest assured that messing up a split pea soup is really hard. Burnt onions. Rancid olive oil. Confusing table salt with kosher flake salt. These are mess ups. But proportions of split peas to onion, carrots, celery can be highly variable as can the amount of liquid. So making this soup is good practice for trying your hand at no recipe cooking.
RECIPE for 3 liters (12 cups)
• 500 grams split peas (2 1/2 cups – generous pound)
• 400 grams mirepoix (1 1/4 cup chopped onion; generous 3/4 cup chopped carrot; generous 2/3 cup diced celery)
• 100 grams olive oil (7 1/2 tablespoons)
• 2 to 3 liters water or stock (8 to 12 cups)
• 12 grams salt (4 teaspoons Diamond Crystal® Kosher Salt or 2 teaspoons table/coarse sea salt)
Start by rinsing the split peas. Then gently sweat chopped onions in olive oil until golden browned and aromatic at least 30 minutes. The longer the onions sizzle softly in the oil the more aromatic they get. Add carrots and celery and sauté another 30 minutes. Now add liquid, split peas, herbs of choice, salt, and gently simmer partially covered until split peas are fully softened and starting to fall apart. Pass the soup through a food mill for an even textured consistency.
INGREDIENTS – Good flavor starts with sourcing the best ingredients. Look for split peas from the most current harvest. Sometimes these dates are hard to find. Store managers often really don’t know and in all due respect many could care less. Best to buy from a trusted supplier. As for the olive oil, no reason to use your best. High heat destroys some of the healthful properties and delicate taste aromatics. I use an everyday extra virgin olive oil from California. As for the liquid use water or vegetable stock or chicken stock in any combination. What’s important is the final volume, about 3 liters or 12 cups.
NUTRITION – I run numbers on all my recipes but I don’t post label results, however I’m happy to send you those numbers if you want them so just let me know.
I prefer using common measure. Most folks can visualize a cup of soup and once you know a cup of soup puts about 230 calories in the bowl, you can do the math yourself. Serving sizes always vary depending on how the soup gets served. Appetizers are usually less than a cup. Main course soup for supper is usually more than a cup. Snackers I’m sure have their own favorite amounts.
Here’re a breakdown for the nutrients per cup that I check for:
• Protein. This soup qualifies as vegan so all 10 grams per cup are plant protein. Ham hocks or bacon or cheese are common additions to split pea soup. They add more protein and you’ll end up with an animal plant protein mix.
• Fiber. Both soluble and insoluble dietary fibers are beneficial from a health perspective. All legumes are fiber rich and split pea soup has lots of fiber, about 11 grams per cup.
• Fat. Olive oil is the source of fat and contribute 35% of the calories as per proportions used above. Using olive oil ensures that the fat profile will be predominantly unsaturated fatty acids. Adding ham hocks or bacon or cheese adds saturated fatty acids and changes the fat profile.
• Salt. Essential for a good tasting soup. Keep in mind however it’s important to salt to your own taste. So the most important step is learning to salt is to know your own salt tolerance. Always keep in mind that under salting is safer. You can use a sprinkling of finishing salt just before serving. Desalting an over salted soup is hard.
Using 4 teaspoons Diamond Crystal® Kosher Salt Diamond for 3 liters soup, one cup of soup has about 410 mg sodium. Sometimes I use only 3 teaspoons of salt which works out to 320 mg per cup. I don’t seem to need as much salt as many other cooks and eaters like to use. For me, a little bit of salt goes a long way. Salting to your own taste is really important because we don’t all taste salt the same way.
Why you may be asking do I specify salt by brand name? The answer is because brand and grind make a difference. So I’m not writing a sponsored post. There are two brands of kosher salt and one brand sits much lighter in the spoon than the other brand so it makes a difference which one you use.
