To make 1 lb These grapes must have certain qualities in order to produce quality raisins. For example, they must ripen early and be easy to dry. Additionally, they must have a soft texture, not stick together when stored, have no seeds, and have a pleasing flavor.
By far, the most widely grown raisin grape is the Thompson Seedless variety. They are used in the production of over half the world's raisins. Ninety percent of these come from California.
The Thompson was first developed in by William Thompson, who created it by taking cuttings from an English seedless grape and grafting them with a Muscat grape vine. The resulting plant produced the first Thompson seedless grapes. It is believed that all of the subsequent Thompson seedless vines came from this original grafting. The Thompson seedless is a white, thinskinned grape, which produces the best raisins available today. Its small berries are oval and elongated. It does not contain seeds and has a high sugar content.
From a raisin production standpoint, Thompson grapes are ideal because they ripen fairly early in the season and do not stick to each other during shipping. The Black Corinth is a grape that originated in Greece, which has become an important variety of raisin grape. These grapes are quite small, spherical in shape, and reddish-black in color. They are thin skinned and nearly seedless. They make good raisins and are excellent for production because they ripen early and dry easily.
Because of their flavor, they are more often used for baking cookies, specialty breads, and fruitcakes than for eating. A cast iron raisin seeder made by A. Williams of Ravenna, Ohio, circa How lucky we are that many of our foodstuffs are already dried, seeded, and otherwise prepared for inclusion in our favorite recipes. We purchase seedless raisins and don't even have the option of purchasing raisins with seeds. However, this was not the case over TOO years ago. Then, seedless raisins expensive were sold alongside those with seeds noted as cheaper and "more commonly used".
One might have saved pennies buying raisins with seeds but invested time in seeding those tiny fruits. One cookbook suggests that Valencia raisins be heated slightly with water in order to plump them, and then cut with a knife and de-seeded by hand! However, enterprising manufacturers produced labor-saving devices for women's kitchen chores, including deseeding raisins. First, the housewife clamped her Boss brand raisin seeder to her kitchen table. Then, she loaded the raisins into the hopper at the top.
As the housewife cranked the handle, the raisins were squeezed between two grooved rubber and toothed-metal rollers, which exposed the seeds. For this reason, dried fruit should only be eaten in small amounts, preferably along with other nutritious foods such as nuts, seeds or yogurt. Raisins, sultanas and currants may improve your digestive health and blood sugar levels, decrease inflammation and lower your blood pressure.

Despite their slight differences in size and taste, each can be used in many of the same recipes and can be easily substituted for one another. Store raisins, sultanas and currants in a cool, dry and dark place such as in the pantry.
Place them in a sealed bag or store them in a glass jar. Raisins, sultanas and currants are extremely versatile foods. They can be eaten plain or added to both sweet and savory dishes ranging from muffins and cakes to curries, salads and cheese platters.

At the end of the day, it is best to choose on a case-by-case basis depending on the recipe or dish and your taste preferences. It is also important to keep in mind that some manufacturers add a preservative called sulfur dioxide to retain the color of the fresh grape. Some individuals are sensitive to sulfur dioxide and experience symptoms such as stomach cramps, skin rashes and asthma attacks after eating it 16 , If you are sensitive to sulfur dioxide, look out for this preservative on the label.
Raisins, sultanas and currants are all highly nutritious and can be used as a substitute for each other in a number of recipes. Look for sulfur dioxide on the label if you are sensitive to this preservative. Raisins, sultanas and currants are different types of dried grapes that are rich in fiber, potassium and antioxidants. Raisins are made from a range of grape varieties. They are dried naturally and are usually the largest of the three. Sultanas are made from seedless green grapes.
They are often dipped in a solution prior to drying, which speeds up the process. They are often the juiciest and lightest in color. Currants are made from small grape varieties. Unlike regular brown raisins, golden raisins are not dried in the sun but in large dehydrators at controlled temperatures, with controlled humidity levels. Golden raisins are also treated with antioxidant sulfur dioxide, which is commonly used for both its health properties and as a preservative in dried fruit and white wine.
And, here's where Harold McGee appears to agree with us: "The result is a much fruitier, lighter flavor. Golden raisins have more flavonoids —phytonutrients found in plants that give them their color and have antioxidant properties—than regular raisins. Otherwise, however, golden and regular raisins are almost exactly identical in their health properties—and both make a healthy snack, just as they did in your lunch box back in the day.
But, when it comes to cooking with raisins—as opposed to baking or snacking —there is no choice. Are they lighter than the grapes?
If any of your grapes rot or get damp, remove them from the tray. Dry grapes will shrivel and turn to raisins, they won't rot. The heat from the sun causes the water to evaporate from the grapes.
It also heats up the sugar, causing it to caramelise. Because the water has evaporated, raisins are smaller and lighter than grapes. The caramelised sugar makes the raisins taste sweet. This straightforward activity shows the change that happens when grapes dry out. Is it a reversible change? Can raisins be turned back into grapes?
