I had some left over cooked prawns I wanted to use up and thought that a sauce would liven them up.
Salsa Romesco is said to have originated from Tarragona, a town close to Barcelona in north-eastern Spain. It is an old Roman town so you can be partly forgiven if you thought that the sauce originated from Rome.
I consulted many sources and there are so many variations to making this Catalan condiment, but the most common ingredients seem to be garlic, red peppers, tomatoes, white bread and almonds. Most interesting is that the recipes from respected food writers, e.g. in Honey From a Weed, (Patience Gray), Mediterranean Seafood (Alan Davison) and Mediterranean Food (Elizabeth David) the main ingredients are tomatoes and the peppers are either paprika or chillies or dried red pepper flakes.
Some recipes include sherry vinegar or wine (rather than wine vinegar). Some have hazelnuts or walnuts as well as the almonds.
There are a few recipes where the bread is first soaked in vinegar and then squeezed dry before it is added to the blend (like when making salsa verde) and others where the bread is toasted in the oven.
Those who are serious romesco – makers make it in a mortar and pestle and also roast or char the tomatoes. If peppers are used these are also charred. I have found references to small red peppers which are often referred to as romesco peppers in Catalonia, so perhaps this is why the name.
Because my grandmothers were Sicilian and this is a Catalan recipe, I cannot say that this is how it is made in my family, however I can give you what has worked for me. There is always room for improvement and I will keep on experimenting.
This sauce is usually associated as a condiment for shellfish and fish. It is also good with grilled and roasted vegetables (especially cold, left over ones that need dressing up the next day).
I usually add a couple of roasted tomatoes to my roasted pepper salads and I conveniently had some in the fridge left over from the night before. I keep roasted garlic covered in olive oil in the fridge, and using up ready made ingredients is often a strong reason why I make certain things in the first place.
4-5 cloves of garlic
1 slice stale sourdough bread
2 large red peppers
1 cup blanched almonds
1 tsp smoked paprika (preferred) or sweet paprika
2 tbsp sherry vinegar or red wine vinegar
2 ripe medium size tomatoes
salt to taste
¼ cup of extra virgin olive oil and ½ cup when you blend the ingredients
water (a little) to thin down the sauce
Prepare the ingredients before hand:
Roast/chargrill the peppers whole, peel, remove seeds and break them into strips. If using fresh tomatoes cut them into pieces. If you are roasting / chargrilling the peppers do them at the same time.
Heat ¼ cup olive oil in a fry pan sauté the bread until golden.
Roast the garlic whole (Preheat oven to 200 °C, wrap in foil and bake). An easier option is to sauté the peeled cloves of garlic in the same frypan after you have pan-fried the bread.
Toast the blanched almonds or alternatively sauté them in the same frypan.
Place the bread, and almonds in a blender and pulverize.
Add the rest of the ingredients and blend until it forms into a thick, smooth-ish sauce. If the sauce is a too thick, add a little water to thin it down.
