You can replace the lake sardines with another fish, either from the lake or from the sea, which in any case has an intense flavour and is well structured.
We have proposed as a side dish a salad with very fresh products, coming directly from the garden: compose your dish with other types of salad, based on how fresh you find them at the market.
Chestnut honey and balsamic vinegar, produced locally, combine perfectly to give aroma and acidity to the dish: if you really cannot find them, do not use poor quality products, simply dress your salad with extra virgin olive oil and white wine vinegar.
