Along with Tuscan Panzanella, Sicilian Caponata is a good way of pulling any mezze or antipasti style meal together and, as such and given how long it keeps, should have a berth in everyone’s fridge through the summer. Most people don’t see caponata as a pickle but it ticks most of the boxes and will keep for at least a week in the fridge. For an even longer life, put it in a jar, press down to get the air bubbles out and pasteurise to a core temperature of 72degC for twenty minutes.
Traditionally served with tafelspitz (an Austrian 'boiled' beef dish much favoured by the Emperor Franz Joseph) this apple and horseradish sauce adds a kick to any meal. It can be adapted to suit your tastes, so whether you like it hot or a little more on the mild side, it's a must.
