I picked up a copy of Ana Patuleia Ortins' latest cookbook Authentic Portuguese Cooking the other day and there are so many recipes in this book that I want to try. This evening for dinner I made Salada de Atum à Moda da Graciosa (Tuna Salad Graciosa Style). If you have the cookbook, the recipe is found on page 204.
Oh my goodness, it is delicious! I'm never mixing mayo with tuna again.
