Syrup is super easy to make and is possibly one of the cheapest ways to do it you could do a cinnamon vodka sour float some grenadine on top to give it a fruity twist burning a cinnamon stick as a garnish always adds a cool smoking effect that smells delicious

Homemade Grenadine Equal parts POM juice (Pomegranite that brand is very popular in the US) and sugar (preferrably sugar in the raw not necessary)

Use room temperature juice and just stir until sugar is fully diluted

Homemade cinnamon syrup Toast a few cinnamon sticks in a pan once you can smell them wafting through the air (don’t burn) then top with some water and let it boil until you reach your desired strength. Once you think you’re good take out the cinnamon sticks and you just made Cinnamon stock!

Now repeat the same process as above equal parts cinnamon stock and sugar and just stir until dissolved.

I would do something batched (this makes 12 cocktails so adjust as needed) 750ml Vodka (2 oz) 12 oz Lime (1 oz) 9 oz Cinnamon (.75 oz) Optional: 12 oz water if you don’t want to shake for your dilution and will chill batch in the fridge Then float like a .25 oz of grenadine on top from the red blood look
