1-First Step: In a large bowl, whisk together the two 3-ounce boxes of flavored gelatin powder and the two envelopes of gelatin powder until they’re evenly mixed. This ensures the powders blend well and dissolve smoothly later.

2-Second Step: Pour in the two cups of boiling water and stir constantly until everything is fully dissolved, which should take about 2 minutes. This step is key for getting that clear, firm texture without any lumps.

3-Third Step: Gently stir in the two cups of cold water to cool the mixture down. Be careful not to over-stir, as this helps maintain the firmness when it sets.

4-Fourth Step: Transfer the mixture to a rectangular container, then use a spoon to remove any bubbles from the surface. This creates a smooth finish, just like at the buffet.

5-Fifth Step: Cover the container with a lid or plastic wrap and pop it in the fridge for at least four hours, or until it’s completely firm. Prep time is just 5 minutes, with the rest being chilling time.

6-Sixth Step: Once firm, cut the jello into cubes and serve it up. It’s ready to enjoy as is or paired with whipped cream for extra delight. This method takes about 4 hours and 5 minutes total.

7-First Step: In a medium pot, whisk together the two 3-ounce boxes of flavored gelatin powder and the two teaspoons of agar powder. This combination gives a vegetarian option with the same firm result.

8-Second Step: Add the two cups of cold water and stir until the powders are dissolved. Unlike gelatin, agar needs heat to set properly, so this is your starting point.

9-Third Step: Bring the mixture to a boil over medium-high heat, stirring constantly for about 1-2 minutes until everything is fully dissolved. Keep an eye on it to avoid boiling over.

10-Fourth Step: Remove from heat and stir in the additional two cups of cold water to cool it quickly. This helps with the setting process without affecting the firmness.

11-Fifth Step: Pour the mixture into a rectangular container and cover it with a lid or plastic wrap. Let it chill in the fridge for three hours or until firm.

12-Sixth Step: After chilling, cut the jello into cubes and serve. This method is quicker in the fridge and perfect for those avoiding animal products. Total time is around 3 hours and 5 minutes.
