1
Grate the zest from 2 large or 3 medium lemons, then squeeze the lemons to obtain the 1/2 lemon juice for the recipe.
-
2
Combine lemon juice and agar flakes in a small non-reactive saucepan (stove method) or a 2 cup heatproof measuring cup (microwave method) and set aside for 15 minutes or until the agar has softened.
-
3
Preheat oven to 350F.
-
4
Grease an 8x8 baking pan.
-
5
Whisk flour and 1/4 cup cane juice together in a medium bowl.
-
6
Add margarine in small chunks and cut in with a pastry cutter until mixture resembles small crumbs.
-
7
Press crumb mixture evenly into the prepared baking pan.
-
8
Bake for about 10-12 minutes in the preheated oven or until lightly browned at the edges.
-
9
Let crumb base cool.

If you will be using the stove to heat the lemon mixture, place the saucepan with the lemon and agar on the burner and bring to a boil over medium low heat.
-
11
Simmer, whisking every few minutes, until the agar dissolves; about 10 minutes.
-
12
If you will be using the microwave to heat the lemon mixture, place the heatproof measuring cup with the lemon mixture into the microwave and cook on high for 1 minute.
-
13
Remove the cup from the microwave and stir.
-
14
Continue to cook the mixture on high at 30 second intervals, stirring well after each time.
-
15
The agar should be dissolved after about 2 minutes of cooking, though this depends on the microwave.
-
16
Now, combine 3/4 cup cane juice with the arrowroot powder in a small saucepan.
-
17
Add the coconut milk and stir together.
-
18
Bring this mixture to a boil over medium heat, stir, then reduce heat and simmer for 1 minute.
-
19
Remove the pan from the heat and add the lemon juice mixture and the lemon zest.
-
20
Place raspberries evenly over the cooled crust in the 8x8 inch baking pan.
-
21
Pour lemon filling into the baking pan on top of the crust and raspberries.
-
22
Turn raspberries with a spoon to coat them with the lemon mixture then let the pan set at room temperature for about 1 hour.
-
23
At this point, either serve the raspberry lemon bars or cover with plastic wrap and refrigerate for up to 3 days.
-
24
Bring the bars to room temperature before serving.
-
25
Dust with powdered sugar, slice into 12 bars and serve.
-
26
NOTE: It is very important that your agar flakes be fresh or their jelling power may be lessened.
-
27
To test your agar for this recipe, put a spoonful of the prepared lemon mixture on a small plate and chill it for 15 minutes.
-
28
The mixture should be firm.
-
29
If it isn't, dissolve some more agar and stir it into your lemon mixture and repeat the test until the mixture jells properly.
