A fresh take on a chilled summer soup! Move over gazpacho – this beautiful creamy Chilled Poblano and Cilantro Soup is delicious on a hot summer day.
Why we love it
Poblanos are likely not a weekly staple pepper in your household. You are probably dropping bell peppers into your shopping cart most often, maybe a jalapeno occasionally, or perhaps a habanero if you really love spiciness. This Chilled Poblano and Cilantro Soup recipe is a great way to get the health benefits of spicy peppers!
Measuring spiciness
Capsaicin is what gives peppers their heat. Luckily, capsaicin comes with numerous health benefits, including helping prevent cancer, improving blood sugar regulation, and even relieving pain. Nutrition Therapist Masters will often recommend adding peppers to the diet if tolerated!
The spiciness of peppers is determined by something called Scoville heat units (SHU). Interestingly, SHU is a measurement of sugar-water. More specifically, it’s the amount of sugar-water needed to dilute an equal part of pepper mash to get to a point where you no longer feel the heat at all.
Here are some examples: a gypsy pepper – a sweet pepper – has a SHU of zero. A poblano has a SHU of 1000 – this means you would need to mix 1 tsp of poblano with 1000 teaspoons of sugar-water to taste zero heat. Now even though that sounds like a lot, a ghost pepper has a SHU of 855,000! There are even peppers that go into the millions with their SHU level.
Although the poblano pepper ranks relatively low on the Scoville scale, it still contains a significant amount of capsaicin.
One thing to note is that bell peppers do not contain capsaicin due to a recessive gene. Although bell peppers do not contain capsaicin, they are still a nutritional powerhouse due to their high vitamin C and beta-carotene content.
What is the spiciest part of a pepper?
The highest concentration of capsaicin is actually in the pith portion of the flesh! This is the membrane that suspends the seeds inside of the pepper. It is often thought that pepper seeds are the spiciest part of a hot pepper. However, the seeds themselves do not contain any capsaicin.
Recipes will sometimes state to remove the seeds to reduce spiciness. This is because seeds often have residual capsaicin on their surface due to contact with the pith. If you truly want to reduce spiciness, make sure to remove the pith.
Expert recipe tip: make sure to taste your poblano when you make this soup! Although poblanos are usually mild, a pepper’s spiciness can change with varying soils, plant growing conditions and the ripeness at which it is picked.
