Recipe adaptation

This recipe is only slightly adapted from the Ottolenghi sumac sauce from the Jerusalem cookbook which uses a combination of sour cream and Greek yogurt in a 2 to 3 ratio. I have always made this recipe with equal amounts of low-fat regular yogurt and sour cream.

I was recently inspired to experiment with the base after realizing how similar the recipe is to classic buttermilk dressing. Given that you can substitute yogurt and lemon juice for buttermilk, you can imagine this recipe will taste like a buttermilk salad dressing with sumac.

Ingredients

sour cream, yogurt, and other ingredients for the sumac dressing.

 

This lemon sumac dressing is made with just a handful of ingredients:

  • Sour cream and low-fat yogurt. See the discussion below about using other dairy products as the base. Buy organic dairy products if you can afford it, because the organic label means that the cows were not treated with hormones or antibiotics.
  • Sumac (see below).

About sumac

Sumac is a tangy spice with a citrus-like flavor made from dried, ground sumac berries. It’s commonly used in Middle Eastern and Mediterranean cuisines, including the classic Mussakhan, a Palestinian chicken recipe with sumac and red onion.

Sumac has been used as an alternative medical treatment for centuries. In small randomized studies, sumac produced mild improvements in fasting blood sugar and non-alcoholic fatty liver disease, among other conditions.

Please see the recipe card below for complete information on ingredients and quantities.

Variations and substitutions

  • For a sumac spice substitution, use za’atar, a spice mixture with sumac, dried green herbs like oregano and thyme, and toasted sesame seeds.
  • Make a sumac vinaigrette. Drop the sour cream and yogurt, and use a half cup of virgin olive oil, one tablespoon of white wine vinegar, and one tablespoon of lemon juice.
  • Vary your base (see below).

The photo below shows bowls of Greek yogurt (#1) and equal amounts of sour cream and Greek yogurt (#2), sour cream and low-fat traditional yogurt (#3), and sour cream plus buttermilk (#4). Depending on what texture and consistency you want, those go from thickest to thinnest.

Recipe tips and tricks

Step by step

Combine all of the ingredients in a small bowl. Taste and adjust the amount of salt, lemon juice, and other ingredients as you desire. There’s no right or wrong. Serve immediately or store in the refrigerator until ready to serve.

In my experiment, the sumac sauce with Greek yogurt alone (#1) had a flatter taste than those made with sour cream. The one with half buttermilk (#4) was the runniest of them all. The sour cream plus Greek yogurt (#2) remained slightly thicker than the one made with traditional yogurt (#3), but tasters thought the flavor was about the same.

What to serve with sumac dressing

The sumac dressing is a great topper for a green salad. Or it’s traditional with fattoush, a Middle Eastern bread salad similar to panzanella except using fried flatbread.

Make it on the thicker side, and use this creamy sumac sauce to serve with meatballs for dinner or in your meatball wrap for lunch. Just pick a recipe for meatballs or veggie balls like Greek chicken meatballs, lamb meatballs or quinoa balls with pine nuts and raisins.

In reality, you can serve the sumac sauce with just about anything. Try it with a recipe for Moroccan chicken and dates, these cauliflower burgers, or fawaffle or another savory waffle with kale.

Recipe FAQs

What does sumac taste like?

Sumac adds a tangy, almost citrus-like flavor to your salad dressings and other recipes.

How should I store this sumac dressing?

Store your sumac sauce in a sealed container in the refrigerator for up to one week. It will not freeze well.

What is a good sumac alternative?

There aren’t many great alternatives to sumac other than za’atar, a spice mixture that includes sumac. If you can’t find either, you can still make a delicious salad dressing without it. It just won’t have the same tangy flavor.
