Open the panel surrounding the drum. Much like you can lift the top of your stove to clean below the heating elements, you can open up your dryer if you're brave and clean the lint that builds up around the drum. Different dryers open in different ways, so check the user manual for your model or look it up online.
The chocolate chip cookie was invented by Ruth Graves Wakefield c. 1938. She owned the Toll House Inn, in Whitman, Massachusetts, a very popular restaurant that featured home cooking in the 1930s.
Created as an accompaniment to ice cream, the chocolate-chip cookie quickly became so celebrated that Marjorie Husted (a.k.a. Betty Crocker) featured it on her radio program. On March 20, 1939, Wakefield gave NestlÃ© the right to use her cookie recipe and the Toll House name.
