Start by bringing 3 cups of water to a rolling boil in a large saucepan over high heat. To enhance the flavor, add a pinch of salt and a splash of olive oil once the water is bubbling vigorously.

Once the water is boiling, carefully add the tri-color pearl couscous to the pot, stirring gently to combine. Bring the water back to a boil, then reduce the heat to low, cover the saucepan tightly with a lid, and let it simmer for about 15 minutes.

After the cooking time is up, remove the pot from the heat and check for doneness. If any excess water remains, drain it off carefully using a colander.

Place the drained couscous back in the warm saucepan, and add the rich butter and freshly squeezed lemon juice. Stir vigorously until the butter melts and coats the pearls of couscous evenly.

Finally, fold in the minced fresh basil leaves, allowing their bright aromatic flavor to marry with the buttery couscous. Serve warm as a vibrant side dish.
