Grab 4-5 fresh lemons and roll them firmly on your counter with your palm pressed down. This breaks down the juice sacs inside, so you'll get way more juice when you squeeze. Cut each lemon in half and use a citrus juicer or your hands to extract 1 cup of fresh lemon juice. Strain out any pulp or seeds through a fine mesh sieve into a measuring cup.
Pour your 4 cups of cold filtered water into a large pitcher. Add the 3/4 cup granulated white sugar and stir until it dissolves completely—this takes about 2-3 minutes of stirring. The sugar should disappear into the water, leaving no gritty texture at the bottom. If you see crystals remaining, keep stirring for another minute.
Add the 1/4 cup pure honey to the pitcher and stir until it's fully incorporated. You'll hear the spoon make a gentle swishing sound as the honey combines with the sugar water. This is when your lemonade homemade base really comes together. The mixture should look clear and smooth, not cloudy.
Pour in your fresh lemon juice and add the 1/2 tsp sea salt. Stir everything together for about 30 seconds. The sea salt might seem weird, but it actually highlights the lemon flavor and cuts through the sweetness so nothing tastes one-dimensional. Taste it now and adjust—if it's too tart, add a tablespoon of sugar. Too sweet? Add a few more tablespoons of water.
Grab a handful of fresh mint leaves (about 2 tbsp) and gently tear them with your hands. Don't use a knife because it bruises the mint. Add the torn mint to your pitcher along with the 1 tsp lemon zest and 1/4 cup freshly squeezed orange juice. Let this sit for 2 minutes so the mint can release its oils into the lemonade.
Stir in the 1/2 cup sliced strawberries. Your kitchen's gonna smell absolutely amazing right now—like fresh citrus and summer morning all mixed together. That warm, bright aroma is your signal that everything's balanced perfectly. The strawberries add a subtle sweetness and make the drink look gorgeous when you serve it.
Fill a serving pitcher with 1 cup ice cubes and pour your lemonade homemade mixture over the ice. Top it off with 1/2 cup sparkling water for a little fizz, then sprinkle 1 tbsp chia seeds on top. The chia seeds add texture and a nutritional boost, but they're totally optional if you want to keep things simple.
