Burger grandma style

My grandma used to make the loveliest burger patties. It's different from the way my mum makes it. Hers is:

Minced pork (about 250gm)
Dark soya sauce
Light soya sauce
Sugar

The minced pork has to be marinated for a few hours. I used about a teaspoon of dark sauce, 1 and a half tablespoon of light soya sauce and 1 tablespoon of sugar.

The patties has to be thin, not those thick kind with juicy centres.

I used my Happy Call pan and it filled it up from end to end at about 1 cm (to 1 and a half cm) thick.

Hubby says it tastes like bak kua. Christopher LOVED it and ate up more than his share.
