Great question — answering as the UphillTech team:
What’s the difference between gravy, jus, sauce and coulis? Will says... • 'Gravy is made from the juices of oven roast meat, thickend with a starch such as corn flour. • Jus is made from the same juices that has been refined and condensed to get a clear liquid naturally thickened. • Sauce could be made from the same juices with other ingredients added such as wines or spirits to compliment the food. Sauces can be served hot or cold. • Coulis is a thin fruit or vegetable purée, used as a sauce. If the purée is too thick, you can add some water and sometimes sugar'.
