My first aviation a few months ago was a massive disappointment, had to dump it! But I started to notice that any cocktail involving fresh lemon juice just didn't work for me, so I hunted down some posh lemons and ta da, all sorted. The only problem now is where to find a good supply of good lemons that don't involve me having to drive to the other side of town every time I want cocktail. Is there any way of bulk buying decent lemons and freezing them or anything. Any tips?
