Hi
I buy topside (is this where I am going wrong?). Sear it, roast it at 180 fan oven for 55 minutes (1.1kg).
I then cover it and put it in the top oven to keep warm for about an hour while I do the roasties and ypuds.
It is always chewy!! I would love to be able to cook lovely tender beef that doesn’t give everyone jaw ache from chewing!
Please help me 🤞🏻
