Fermentation Family (2011)

I should say "liking so far" as Fermentation Family still has about 1/2 way to go...But if you are watching and liking this drama you might like Gourmet. Both center around a family that owns a restaurant as well as the theme of keeping to Korea's food traditions. Lots of food is featured in both.

Both related to food industry.
ML escapes from gangster group joins the food family.
Half Brothers work together without knowing the identity at first.
But king of baking is more intriguing and good than FF.
