Looking for rasberry long island recipe that tastes like lemonade.

So my sisters got me into this drink but the problem is it had to be made in the right way. theoretically it was basically a long island ice tea where the coke portion was replaced by rasberry liquor (schambourg) but doing that does not taste right. I think it did not have tequila and there may have been something with sour or bitter or I don't know what. The key though is it was a drink with a bigger kick than a long island yet literally tasted like you were drinking lemonade (which I know given the name is ice tea is kinda ironic)
