Measure out all ingredients and have them within arm's reach of your stove. Chop the pistachios coarsely and set aside. This mise en place approach ensures you won't be scrambling for ingredients while the oatmeal is cooking, which requires frequent stirring and attention.
Bring 3 cups water, 1 cup whole milk, and 1/2 teaspoon salt to a boil in a medium pot over high heat. The salt enhances the subtle flavors of the oats and dried fruit, so don't skip it. Once you see a rolling boil, you're ready to add the oats.
Add 1 1/4 cups old fashioned rolled oats and 1/4 teaspoon ground cardamom to the boiling liquid, stirring well to prevent clumping. Reduce heat to low and simmer for 25-35 minutes, stirring frequently—I recommend stirring every 3-4 minutes to ensure even cooking and creamy texture. The oatmeal will gradually thicken and the oats will soften as they absorb the liquid.
Remove the pot from heat and stir in 1/2 cup diced dried apricots, 2 1/2 tablespoons apricot jam, and 1/2 teaspoon fresh lemon juice. The lemon juice brightens the sweet apricot flavors and prevents the dish from becoming one-dimensional. Let the oatmeal sit for 2-3 minutes to allow the apricots to soften slightly and the flavors to meld together.
Divide the warm oatmeal from Step 4 between bowls. Top each serving with the chopped pistachios from Step 1 and drizzle with 1 tablespoon pomegranate molasses divided among the bowls. The pomegranate molasses adds a tart, sophisticated finish that cuts through the richness and brings everything into beautiful balance.
