Substitutes:

• Soju: If you don't have Soju, you can use vodka for a similar but slightly more robust flavor. I've also tried using white rum, which adds a different but pleasant twist.
• Orange Juice: Freshly squeezed orange juice tastes best, but store-bought works fine too. In a pinch, I've used pineapple juice for a tropical variation.
• Grenadine: If you're out of Grenadine, you can quickly substitute pomegranate juice with some simple syrup. It's not the same, but it works well.

Making a Pitcher of Soju Sunrise:

• Scale: To make a pitcher that serves 8, multiply all the ingredients by 8. That would be 16 oz of Soju, 32 oz of orange juice, and 4 oz of Grenadine.
• Mix: In a large pitcher, combine the Soju and orange juice first. Stir well.
• Serve: Pour the mixture into ice-filled highball glasses, slowly add a splash of grenadine, garnish with an orange slice or cherry, and serve immediately.

Making it Non-Alcoholic:

• Soju Substitute: Use a non-alcoholic spirit that mimics Soju's flavor profile; these are available and do a good job.
• Proceed As Usual: Use this non-alcoholic substitute instead of Soju, follow the original steps, and enjoy a non-alcoholic version.

Making it Vegan:

• Ensure Ingredients Are Vegan: Most commercial grenadines are vegan, but always check the label. Some brands might use animal-derived colorings.
• Use Vegan-Friendly Garnishes: Stick to fresh fruit like orange slices or cherries for garnish to keep it vegan-friendly.
