Over time I have tried different recipes for focaccia. I have found the one that I will be sharing with you, the best and has been adapted from an old recipe, by increasing the hydration and letting the dough rest overnight in the fridge.
Once you have mastered the classic salt and rosemary, try a different variation of toppings from tomatoes and goats cheese, to vegetarian focaccia or a more complex with figs, blue cheese and walnuts.
The ingredients are for a 39.2 x 26.7 x H2.5 cm oven dish you can find here and which I highly recommend
Fast action yeast is a great substitute for fresh yeast, but adjust the quantities depending on the temperature by a 1/4 of tsp more
