In my experience, adding a small amount of olive oil to cookie dough or icing can give a unique texture and flavor twist that isn't overpowering but definitely noticeable. When decorating cookies, especially intricate designs, the slight oiliness can help in smoothing icing layers or creating a glossier finish. However, it's best to use it sparingly, as too much olive oil might cause the icing to become too soft or runny, which can be tricky when working with detailed patterns. Another fun tip I learned is incorporating olive oil into martini-inspired cookie flavors, where the oil's subtle fruitiness complements herbal notes like rosemary or thyme. This makes your decorated cookies not just visually appealing but also delightfully flavorful. For anyone exploring #decoratingcookies, experimenting with tiny amounts of olive oil might lead to some unexpectedly great results. It's a little secret some bakers use to elevate their creations, so if you’re curious, try a 'tini bit' and see how it works for your style and taste preferences!
