Raspberry Chiffon Cake

Raspberry Chiffon Cake

This Summer’s featured ingredient is the Red Raspberry.

The red raspberry (Rubus idaeus) is an edible fruit of the Rose Family.  A raspberry is actually not a single berry, but a cluster of 50 to 150 tiny stone fruits, or drupelets, each containing a seed.  1

Raspberries

 

 

 

 

 

Red raspberries are indigenous to both Asia and North America.  They are believed to have been first gathered wild on the Asian continent by the Trojans in the foothills of Mt Ida in ancient Turkey.  Roman agriculturalist Palladius wrote about their domestication in the 4th century.  Romans are thought to have initiated the spread of raspberry cultivation across Europe.  2

In early Medieval Europe, raspberries were mainly eaten by royalty.  Their juices were used in paintings and manuscripts.  All parts of the plant were used in medicines and topical treatments to treat such ailments as diarrhea and menstrual cramps.  King Edward (1272-1307) is recognized as the first person to call for their general cultivation, and by the 1700s raspberries could be found growing in gardens throughout Europe.

American Red Raspberries were also used by the Native Americans in traditional medicines and eaten fresh or dried for ease of transportation. European settlers in America brought their cultivated raspberries to the new colonies.  George Washington is said to have cultivated raspberries at his Mount Vernon estate.  After the Civil War, major production of raspberries emerged across the country.  Today, the leading producing regions for red raspberries are Washington, Oregon and California.  3

Raspberries are typically in season from June to October, depending on the region.  Often local farms will offer a seasonal You-Pick berry patch one can visit with information online.  In rural areas, there can be wild berry patches where one can forage.  When first visiting a wild berry patch, go with an experienced berry picker who can positively identify the raspberries.  While there has never been a clustered drupe berry (i.e. raspberry, blackberry, boysenberry) identified as poisonous, there are many berries that are poisonous!  Never eat a berry that has not been identified as edible.

When picking red raspberries, select plump, firm, fully red berries.  Unripe berries will not ripen once picked.  Gently grasp the berry with your fingers and thumb, and tug gently.  If it is ripe, the berry will easily come off in your hand, leaving the center part attached to the stem.  Avoid touching the stems of the berry plants, as they can have tiny stickers.  Fill containers no more than 3 inches deep to protect the berries.  Refrigerate berries as soon as possible after picking for up to three days.  Wash berries only when ready to use them, as they will quickly mold after exposure to water.  Surplus berries can be frozen in airtight containers or freezer bags for up to 3 months.  4

Red raspberries are a rich source of manganese, vitamin C, fiber and numerous bioactive compounds that research indicates may have antioxidant, cardio-protective, neuro-protective, and anti-cancer effects.  Raspberries also contain B vitamins, vitamin K, potassium, calcium, iron and magnesium.

Red raspberry seeds are high in vitamin E, and omega-3 fatty acids.  Raspberry seed oil, when used topically, has a sun protection factor (SPF) of 25-50.  2, 5

11.  Bake 60-80 minutes until springs back to light touch, top cracks and appears dry.  Unlike most cakes, it is better to over bake slightly than under bake slightly to ensure the cake is adhered to the sides of the cake mold, and will survive inversion.

13.  To unmold cake, turn pan right side up, and run knife around outer and inner edges.

14.  Grasp inner tube and pull cake out of pan onto counter.  Cut bottom free.

15.  Invert cake onto serving plate.  Gently twist tube to remove.

16. Cut slices of cake and place on individual plates or bowls.   Top with whipped cream, raspberries, raspberry glaze, and toasted sliced almonds.

  1. Am I correct in assuming that the flour mix should be mixed into the yolk mixture, then the meringue folded into that? Your directions don’t actually say.
