Make sure the loin is at room tempreture and also pat dry
I use my cast iron pan for this as it is great for searing and I can place it in the oven.
Pre heat the oven to 180°C. Get the pan very hot.
While waiting for the pan to heat, coat the loin with olive oil, salt and only a little pepper
Time to sear. We are sealing the lin and making sure its niely charred each side. Usually 1 minute per side is fine but keep an eye on it.
Place in the oven, the estimate here is 7 - 10 minutes
Check for internal tempreture of 50 to 55° dependong on your preferece. Remove from the pan and oven and set aside to rest. Very important!
Now the sauce. If you have your own favourite sauce, go ahead! Slightly sweeter, fruity sauces go well.
Using the same pan, place on medium heat on the hob. Add the wine and deglaze the pan - scraping up the bts and pieces. Let it bubble along for about 6 minutes
Meanwhile, mix the water, stock and flour together, Add to the pan and let it simmer another 10 minutes or so, or when you see it starting to thicken
Mix in the blackcurrent jam, and break the chocolate pieces into the sauce. Mix quickly for a minute.
Taste. Add salt and pepper to taste and also sugar if you think it needs it. Simmer for a minute until it is the right consistency
Slice the loin and spoon over the sauce. Enjoy!
