Rideau Hall Garden Chai-flavoured Squash Velouté

Why I Love This Recipe
This is a really quick and fantastic recipe shared by Rideau Hall's chef, Louis Charest. It is a squash soup that will impress your everyone's taste buds. If you like chai tea, you'll love this recipe. If you want to make a nice garnish and use up your squash seeds, try the chef's Maple, Chili and Sea Salt-roasted Pumpkin Seeds (you can also try his lemon balm apple chips)- both recipes can be found here: http://ottawacitizen.com/life/food/a-rare-taste-of-rideau-halls-kitchen-garden
