Falernum: Falernum is either an 11% ABV syrup liqueur or a nonalcoholic syrup from the Caribbean. It is best known for its use in tropical drinks. It contains flavors of ginger, lime, and almond, and frequently cloves or allspice. It may be thought of as a spicier version of orgeat syrup. The form can be alcoholic (syrup liqueur) or nonalcoholic (syrup). Versions with alcohol are generally lower in proof (≅15 ABV), adding rum and emphasizing the clove, ginger, or allspice flavoring aspects for use in mixing cocktails, typically tropical or tiki drinks. It is also enjoyed on the rocks. Depending on sugar content, the consistency is often thick and is therefore sometimes referred to as "velvet falernum" because of the feeling it leaves on one's tongue. Brands vary and the color can be white to light amber, and it may be clear or translucent.
Lime juice: Lime juice is a common ingredient in many cocktails, as it adds a tangy, citrus flavor. It is often used in combination with other ingredients such as sugar, alcohol, and other fruit juices to create a balanced, flavorful drink. Some popular cocktails that use lime juice include Margaritas, Daiquiris, Gimlets, and Mojitos. Lime juice can also be used as a garnish for drinks like the Margarita, and is also used in many non-alcoholic drinks like limeades and iced teas. It's a versatile ingredient that is used in many drinks and can add a refreshing taste to any cocktail.
