A great sauce is the key to a great dish – and while these days you can learn to cook online, perfecting an incredible sauce takes much more than YouTube! Partner with Diane Manteca at the Boston Center for Adult Education at 122 Arlington Street on Thursday, July 30 from 6 – 9 to master wonderful summer sauces. Students will team up with chicken, red meat, pasta, or fish to create Heirloom Tomato and Garlic Ramps, Wild Mushroom & Marscapone, Kale & Pistachio Pesto, and Sicilian Eggplant with Grilled Peppers. $52 (BCAE members $45) with an $18 materials cost.
