Pour the strawberry gelatin into a mixing bowl.

Add the boiling water and whisk until the gelatin is completely dissolved, about 2 minutes.

Stir in the cold water and mix well.

Add the lemon juice to the mixture and give it a good stir.

Gently fold in the sliced strawberries, ensuring they are evenly distributed.

Carefully pour the gelatin mixture into a refrigerator-safe container or mold.

Place the container in the refrigerator and let it chill for at least 2 hours.

If using a mold, run warm water over the outside of the container to release it.

Carefully invert it onto a serving plate.

Slice the gelatin into squares or wedges and serve chilled.
