Knowledge: Karen Warren, a veterinarian, made no-fuss dog kibbles and the recipe can be found on her blog. On the other hand, Ruth Wakefield's cookie recipes are available in her museum.

Conversation:
I just love to bake. I'm always in the kitchen baking something.
Oh, that's nice. Bread is the most commonly baked item. What do you like to bake?
I really like to bake cakes, there are so many options with that. Bread is most common but I have not tried my own yet
Oh, OK. Well, a person who bakes professionally is called a baker.
Yes, that's true. I like to bake chocolate chip cookies. Do you know how they came about?
Chocolate Chip cookies actually originated in the United States around 1938. A lady named Ruth Wakefield chopped up bits of a Nestle chocolate bar into a cookie. Thus, the chocolate chip cookie.
Oh, I did not know she made it! wonder where I can find her recipes. Do you know?

Response: Ah yes. I heard Ruth Wakefield's cookie recipes are available in her museum.
