Candy oils (a.k.a. candy flavorings) will add a more intense fruit flavor. They will taste more like store-bought gummies. Candy oils are available online and at candy-making stores, grocery stores, and pharmacies. They come in small bottles that typically cost $1-$3. Online they can be more expensive. I particularly love LorAnn Green Apple, Cherry, Grape, Lemon, and Orange, but dozens of flavors are available.
