Concentrated Blueberry Syrup (Blueberry Sharbat)
Blueberry gives a sweet syrup with a touch of acidity and a rich purple color.
We build this concentrate on a method in which the blueberries are cooked with sugar and water until they break down into a syrup, then it is strained and diluted with water or soda in drinks.
Combine the blueberries with the sugar and cooking water in a pot over medium heat, and leave it until it starts to boil, then lower the heat and cook it gently for about five minutes until the blueberries burst and release their juice, as gentle cooking breaks down the blueberries and extracts their deep blue color without turning it into a thick pulp.
Add the lemon juice, stir, and cook for one more minute until the consistency becomes a syrup, as the lemon brightens the blueberry and balances its sweetness with a touch of acidity.
Remove the pot from the heat and let it settle for a few minutes, then strain it through a fine sieve and gently press the pulp to extract the remaining juice, as straining gives a smoother syrup suitable for drinks.
Let the concentrate cool completely, then transfer it to a glass bottle and chill it in the refrigerator, because serving it cold brings out the freshness of the blueberry.
Pour about a third of a cup of the concentrate into a glass and top it up with cold water or soda and ice cubes, then stir it, as this is a concentrated syrup that is stored and diluted at drinking time.
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.
A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.
* Percent Daily Values are based on a 2,000-calorie diet per FDA food-label reference values — your daily needs may be higher or lower. Values are derived from the recipe's ingredients via the USDA database.
The most common problems when preparing Concentrated Blueberry Syrup (Blueberry Sharbat), and how to fix them:
Add a little hot water and stir, as blueberry thickens quickly and the water returns it to a syrup consistency.
Add a little more lemon juice or dilute with more cold water at serving, as the acidity and dilution balance the sugar.
Keep the concentrate in a tightly sealed glass bottle in the refrigerator for up to three weeks.
Freeze the concentrate in ice-cube trays for up to three months and thaw what you need at serving.
