In a small saucepan, melt the butter, then add the shallot, garlic, ginger, cardamom, cinnamon, cumin, turmeric and oregano. Cook on very low heat until brown spices start forming in the bottom of the pan, about 10 minutes, stirring often and making sure it does not burn.
Strain the butter through a fine mesh sieve lined with cheesecloth, into a clean jar.
