Cooking a roast dinner

Thanks kitty that will be sure to impress.

I always add some anchovies when roasting lamb, I love them on pizzas too.

Daft question, what exactly do the anchovies add to the dish ?
I've seen Sainsbury's adds in the press saying add them to your shepherd's pie, why

I think anchovies add a sort of deep saltiness.

Kitty regarding left over anchovies in the little peel-back tins - I find them fiddly and leaky and so now buy a jar from Waitrose:

Jar

Works out a bit more expensive but so worth it - when the anchovies have finished I continue to use the infused olive oil to fry eggs

I don't always use the end of the tin so I buy the cheapest possible in case I have to throw it away. I use loads of cling film before I put them in the fridge. I have bought the jars but they take even longer to use in my experience.

But then we established on another thread that I am profligate and have more money than sense!!
