Slice the bread.
Remove the crust.
Using a cook knife, chop the bread to make breadcrumbs. The aim is to obtain roughly chopped breadcrumbs, of uneven size and shape. This will give the dish its final rustic appeal! (do not use the food processor).
After 5 minutes chopping, your breadcrumbs should be, more or less, like this.The preparation of the anchovy sauce is very quick so I suggest you fill, just now, a large pan with approximately 4 litres (1 gallon + 5/8 cup) of water and add salt (10 g for each litre of water - 1/3 ounce for every 4 1/8 cups of water). While you are bringing the water to the boil, do as follows.
Cut the anchovy fillets in small pieces, crush the garlic with the large blade of a knife, roughly chop the parsley and cut the chilli into rings (discarding the seeds).
To prepare the sauce, take a large sauce pan and gently infuse the oil with the garlic (crushed), on low heat, until the garlic become golden in colour. Tilting the pan will allow you to better infuse the oil and it is less likely that the garlic become burned.
When the garlic is golden in colour, remove it from the pan and discard the garlic.
Meanwhile the water to boil the pasta should be ready (fast boiling). Quickly throw the pasta into the pan and carry on with the anchovy sauce. From here, check your time because you will have roughly 10 minutes to complete the sauce.
Add the anchovy into the sauce pan.
Stir to help in dissolving the anchovy. The low heat will give you time to break down the anchovy without the risk of burning it. This process should take less than two minutes.
When the anchovy is dissolved, add the chilli.
Stir and sweat the chilli for a minute or two (still on low heat).
Add the parsley.
Stir for few seconds and reserve the sauce into a glass bowl.
Set the bowl aside, just for few minutes.
We are left with the sauce pan empty. Bring the pan to medium/medium-high heat.
Add the breadcrumbs into the sauce pan.
Toast the breadcrumbs until slightly brown. The process should take about two or three minutes. When the breadcrumbs are toasted, remove the pan from the heat.
Meanwhile, the pasta should be ready (cooked al dente). Drain the pasta and return it back into the large pan you used to boil it.
Add the sauce, you have previously set aside, to the pasta.
Add the breadcrumbs to the pasta and give the pasta a big stir. However, keep some breadcrumbs (a scant tablespoon for each plate) for the final garnish.
Here is the final dish.
