Amédée-François Frézier Amédée-François Frézier Amédée-François Frézier (1682 – October 26, 1773) was a French military engineer, mathematician, spy, and explorer who is best remembered for bringing back five specimens of "Fragaria chiloensis", the beach strawberry, from an assignment in South America, thus introducing this New World fruit to the Old. As described by G.M. Darrow, Frézier's ancient surname was derived from "fraise", the French word for strawberry. A story relates the surname is derived from the fact that Julius de Berry, a citizen of Anvers (i.e. Antwerp), was knighted by Charles the Simple in 916 for a timely gift of ripe strawberries.
Fruit preserves pH adjusting agent or an antifoaming agent. Both types cannot contain apple or rhubarb fruit. Though both types of jam are very similar, there are some differences in fruit percent, added pectin and added acidity. Fruit jam must have at least 45% fruit and may contain added pectin to compensate for the natural pectin level found in the fruit. Fruit jam with pectin need only contain 27% fruit and is allowed to contain added acidity to compensate for the natural acidity of the fruit. In the U.S., jelly (from the French "gelée") refers exclusively to a clear or translucent fruit
