In a medium saucepan, melt the butter. Mix in flour, cooking until lightly golden, 1-2 minutes. Add the broth and whisk continuously until very smooth. Bring to a boil to thicken the sauce. Reduce to low heat and let simmer 5 min (stirring occasionally). Add the cream, cumin, paprika, garlic, salt, and pepper, to taste. Remove from the heat.
