Soak your cashews in boiling water for 15 minutes. Drain and set aside. This step makes the sauce creamy and smooth without any dairy.
In a skillet, cook the diced onions, red bell peppers, and jalapeños over medium heat for 7–9 minutes. Add a tablespoon of water to help them soften evenly without sticking.
Stir in the minced garlic and sauté for about a minute until fragrant. Remove the skillet from heat until the sauce is ready.
Combine the soaked cashews, plant milk, vinegars, vegetable broth, hot sauce, nutritional yeast, and spices in a blender. Blend on high for 1–2 minutes until completely smooth.
Return the skillet to the stove, add the sauce, cornmeal, optional pickled jalapeños, and corn. Simmer for 5–7 minutes on low until thickened and creamy. Serve hot.
