Don't leave out the lemon zest; it finishes the dish with a bright flavor boost. I substitute the squeezable ginger paste and get delicious results. Don't get heavy-handed with the spice, but rather, let the flavor of the carrot and ginger shine. The Instant Pot version is not quicker but more convenient. While developing taste by sauteing the aromatics is necessary for the stovetop method, the Instant Pot locks in the flavor, thus eliminating that step.
