You failed to mention to allow cucumber to drain or squeeze in a cheese cloth to remove excess water. I am sensitive to cucumber so I used English cucumber because they are milder and shredding because it incorporates more flavor without belching. Make a big batch it's great for salad.
Garlic lover here. Let it refrigerate overnight & 3 cloves was too much garlic for me. I imagine 1.5-2 cloves would be perfect for other garlic lovers though. Other than my experimental mess up it tastes great.
