If you find yourself with plenty of lemons then this recipe for lemon slice - or lemon bars - is just the ticket. Around here, the lemons come in winter - and being Meyer lemons (thin skins) they don't like hanging around (Peter).

Extra Lemony Lemon Slice

Ingredients

Crust
2 sticks butter ( 8 oz  ) at room temperature (or carefully warm - not melt - in microwave)
1/4 cup brown sugar
2 cups ( bit less than 2 packs ) Graham Crackers (or, in Australia, Arnott's Shredded Wheatmeal bikkies)
Optional: add 1/2 cup finely chopped pecans
3/4 cup flour

Note: I like the graham cracker crust.  You can also do a flour crust.

Very few and very simple ingredients.
Filling
6 eggs
2 cups sugar
1.5 cups lemon juice (about 6-8 lemons, depending on size/juiciness)
Zest of ALL the lemons
3/4 cup flour
Preheat oven to 350 degrees F.

Method: Crust

1. Procure your 9" x 13" glass baking dish and line with parchment paper.  Spay some cooking spray on it.
2. Cream the butter and the sugar with your electric beater till the mix is light and fluffy.

3. Crush the graham crackers. I like to put them in a zip lock bag then use a rolling pin.  You can also just use your food processor.
4. Using your mixer, add in the flour and the graham crackers in batches.
5. Using your hands or the back of a large metal spoon, press the crust mix into your baking dish trying to make the layer as even as possible.
6. Bake the crust in the oven for 15-20 minutes till golden brown. (It's already brown so you may not see the "golden brown" color.)

Method: Filling

7. Crack the 6 eggs into a bowl and whisk them together with the sugar, lemon juice, lemon zest and flour.
8.  Let the crust cool then pour the mixture into the baked crust. (If you poor the mixture into a hot crust it may cause it to break up and cloud you lemon mix.)
9. Bake mixture for 30-35 minutes then remove from oven and let cool.

10. When cool, you should be able to remove the whole thing - paper and all - from the dish.  Using a sharp knife, cut the whole into parts.
11. Before serving, you can sprinkle some icing sugar over the top (using a fine strainer).
I made an error with this slice on the left: I poured the mixture when the crust was hot causing it to break up and "muddy" the filling.
