Add 3 tablespoons of water to a small bowl.
Add 1 tablespoon (20 grams) of miso paste and 2 tablespoons (45 grams) of jam, jelly, or preserves to the bowl.
Mix everything until it's incorporated and set aside.
Heat enough oil to coat the bottom of a small pan over medium heat.
Add ½ teaspoon (3 grams) of garlic and ½ teaspoon (3 grams) of ginger to the hot oil and stir until fragrant, about 30 seconds.
Add the miso mixture and cook for 2 to 3 minutes or until slightly thickened.
Turn off the heat, add 2 tablespoons (28 grams) of butter, and keep the pan moving until it's emulsified in the sauce.
Season with a squeeze of lemon juice.
