RANDY SHOREs new cookbook Grow What You Eat, Eat What You Grow is now available at Chapters, Book Warehouse, Barbara-Jos Books to Cooks and Whole Foods. So, my Top Secret Garcinia experience was neither super impressive, nor super disappointing.

In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception. The transformer used at the input and output of each intermediate-frequency amplifier stage in a superheterodyne receiver for coupling purposes and to provide selectivity. Abbreviated i-f transformer.
