pavlova wreath inseasontoday.com ... used the Grandma’s Pavlova recipe, which has white vinegar and cornflour added to the meringue mixture. The texture is marshmallow-like in the centre and crisp outside. It is less brittle than pavlova recipes without the vinegar and cornflour. .... Personally, I like my wreath festive looking so I used fresh strawberries, fresh mint leaves and frozen mixture of blackberries, raspberries and blueberries to decorate the wreath.
