Place all ingredients, except 1 cup water and agar, in blender and blend until smooth.
Scrape down sides of blender with a spatula and blend again on high speed until mixture is very, very smooth and creamy. (I recommend using a high-quality blender to get the mixture very smooth and creamy.) Set aside.
In a small saucepan, stir agar into 1 cup water. Cover, and heat over medium-high heat until boiling. Reduce heat and simmer for 60 seconds. Remove from heat.
Immediately pour agar mixture into ingredients in blender and blend until thoroughly combined. Scrape pan with a spatula to get all the agar mixture.
Promptly pour mixture into an oiled dish and refrigerate until chilled and set.
If using a heavy-duty blender, the carrot in this recipe can be placed in the blender jar whole. No need to slice it.
