A Preview Of "AT HOME WITH UMAMI" | This vibrant and earthy green tea dressing is packed with anti-oxidants and healthful flavours. To taste the real benefits of this vital vinaigrette try to use a good cold pressed extra virgin olive oil, I often replace half of the olive oil with an omega 3,6,9 oil from the health food store and add a spoonful of raw cacao nibs with the herbs. The umami secret in this recipe is the mixing of all five basic tastes, sweet, sour, bitter and salty and taste how combined with the green tea they bring out the umami in the asparagus.
