Turtledove Pesto Co. has launched a range of all-natural dips that are trans-fat free.

Julie Lapham, the founder of the US firm, said that the key to the growing popularity of the brand is quality.

"I'm passionate about the ingredients that go into my Pestos and Pesto Dips; fresh herbs, vegetables, sweet cream butter, and the time honoured process I follow in preparing small batches by hand, I never will sacrifice quality to make a less expensive Pesto or Pesto Dip," Lapham said.
