When an individual not only retains elements of his or her original culture but also adapts to elements of a new one, he or she is adopting the approach to acculturation?

Integration

In normal approach to acculturation, new comers that come to a new society will forget their previous cultural identity and started to adopt the characteristics of the dominant culture.

In Integration approach to acculturation on the other hand,  Those newcomers will still make an effort to adopt the characteristics of the dominant culture, BUT they are not letting go of their culture of origin.

But rather than using the original ingredients that used In Korea, they started to add additional ingeridients such as Cheese to their oriental fish to appeal more to American market.
