Minty With your avocado half, you'll need a lovely mozzarella. Every week, we invite England's leading mozzarellieri to offer up their cheeses for audition. You probably don't have the time or the inclination or the power within the catering industry. Don't worry. Just buy half-a-dozen Battipaglia buffalo mozzarella from your local Italian deli, take them home and audition them yourself!
