Topside chunks still tough after 2 hours cooking?

I've made a Massaman curry with Topside beef. I've cooked the curry for 2 hours now, the meat breaks up when pushed with a spoon but feels very tough and firm and not soft and falling apart like I hoped.

Any idea whats' wrong and if I can fix it somehow?

More details:

I seared the chunks prior to adding them to the curry.
The curry has been cooked on low-to-medium heat for 2 hours
The meat was slightly still frozen when seared (still easy to cut with a knife just a bit icy)
I've cut the meat into chunks of about 2 inches x 2 inches x 1 inches
The meat was advertised as lean top side

Topside is a good cut of beef for slowly braising, which is what you're doing here. I assume you're following a recipe that calls for 2 hours of cooking? Many recipes for braised meat dishes tend to understate the amount of time it needs to be cooked to become tender (just like how they will tell you you can caramelise onions in 20 minutes). 2 hours is a very short time for this kind of dish. I tend to cook braised beef for anywhere between 4 and 6 hours to get it tender enough to fall apart. It takes time for the chemical reactions that you're after to take place. Give it at least another two hours, and it will be much better.

Why is my topside beef tough?

Beef has a lot of collagen in it, and that's what makes it tuff. If you cook it fast, the collagen contracts, and squeezes out some of the moisture. On the other hand, if you cook it real slow, the collagen can disolve/melt, and it actually adds to the mouth feel.

Does beef get softer the longer you cook it?

By its very composition, meat poses a challenge to cooks. The more you cook muscle, the more the proteins will firm up, toughen, and dry out. But the longer you cook connective tissue, the more it softens and becomes edible.

Why is my beef still tough?

Additionally, overcooking meat, even meat that comes from the more tender muscles, can make it tough. That's because heat causes the proteins in the meat to firm up. Overcooking also basically squeezes the moisture out of the meat, making it dry as well as tough.

How do you cook topside so it is tender?

Cutting the beef into large chunks and gently cooking it in a stew is a great way to cook topside. It will become soft and should fall apart if cooked for long enough. Topside has less fat running through it than other cuts making it leaner, and therefore it would work in a lower-fat stew, casserole or curry.
