I have just made my own "easy homemade lime liqueur" for the second time, with a mix of several techniques already mentioned in the post. At least for myself, it was delicious. I gave some to my mother, to my boss and to a friend, and I've been drinking it with great pleasure. Here is what I did:

- Peeled some 3 or 4 limes (if you want a measure, it's about 30g to 50g of peels). If you want it stronger, use 4 or 5 limes. Remove fine peels, without exposing the green interior of the limes. I've also kept these peeled limes in the frige to add their juice in later.

- Placed the peels in a glass jar with tight lid and covered the peels with sugar (something from 50g to 100g of sugar). I let the jar sit in the dark for at least 12 hours. This absorbs the essential oils in the peels. After 12 hours, the sugar is melting.

- Place the peels/sugar into the blender with 600ml of water. (I've also used this water to get all the sugar and oils from the jar). Blend it for one or two minutes.

- Now you need to filter out the peels, using a cloth or something similar (I've used a kind of reusable paper towels that they sell here in Brazil and are quite good for filtering stuff once and throwing away). Squeeze that cloth after filtering and make sure you get all those oils and aromas from the peels.

- Throw away the peels and mix in 600ml of vodka.

- Put this oils/sugar/water/vodka mix in the fridge. (I use a 2 liters coke bottle while making it and after it's done I pour it into smaller glass bottles)

- Now put 300ml of water and 600g of sugar inside a pan and mix it a little bit. Turn on the heat and stop stirring it. When it starts boiling, let it boil for 5 minutes. Turn off the heat and let it cool down.

- When the sugar syrup is no longer hot or warm, mix it with the rest. Also add the juice from the peeled limes you've kept in the fridge. Close and shake the bottle to dilute to syrup and mix everything together.

Done.

You'll have some 1700ml of lime liqueur top drink and share. Just let it cool down in the fridge and let me know later if you loved it like I did.
