In a pot, heat a drizzle of oil on MEDIUM until it sizzles but has yet to reach its smoking point.
Add the flour and spices and vigorously whisk.
Carefully pour in the stock, followed by the tomato paste and a dash of salt and pepper.
Maintain a steady whisking motion as the mixture thickens. Once it has thickened, take it off the heat immediately and continue whisking until it cools a bit.
