Coat a large high-sided saute pan over medium-high heat, with the olive oil. Add the lentils, garlic cloves and bay leaves with 4 cups water or just enough to cover. Bring the water to a simmer
and lower the heat. Simmer the lentils, uncovered, until they are tender, about 25 to 30 minutes. (Chef's Note: If you need to add more water for the lentils
to finish cooking, add a little at a time. There will be more flavor in the lentils if you cook them and end up with very little liquid at the end of the process. The flavor will be in the lentils instead of down the drain
with the discarded cooking liquid!) Once they are cooked but still somewhat "al dente
", set them aside to cool. Remove and discard the garlic cloves
and the bay leaves. Season with just a touch of salt and pepper, to taste. Retaste, but hold off on reseasoning until serving.
Add the duck fat to a large saute pan over medium heat. Add the onions
, season with salt, to taste, and allow them to caramelize
When you are ready to serve add the lentils to the sauteed
cipollini onions. Stir to coat the lentils with the duck fat. Taste and season with salt, if needed, and stir in the vinegar
. Transfer the lentil mixture to a serving bowl and serve with duck
and green peppercorn glaze
, if desired.
