Butter and flour a 9 by 5 inch loaf pan.
Preheat oven to 350 degrees F.
In a large bowl rub together with your fingers:
2 T lemon zest
6.90 oz (~ 7/8 c) granulated sugar
Whisk in:
1/2 c olive oil
1/2 c "egg product" or 2 eggs
In a smaller bowl combine:
6.70 oz (~1 1/2 c) all purpose flour
1 t baking powder
1/4 t baking soda
In a measuring cup, combine:
2 T lemon juice
1/3 c buttermilk (see note above) or plain yogurt
A little at a time, alternately add the flour and lemon juice mixtures to the oil and sugar mixture.
1/3 c poppy seeds
Mix well then pour batter into the prepared loaf pan and smooth top to even.
Cook about 50 minutes or until a small skewer inserted into the cake comes out clean.
Let cake cool for 10 minutes, then remove from pan and brush with lemon syrup:
2 T granulated sugar
1/4 c lemon juice
(Note: Perelman uses 2 T sugar and 1/3 c juice and pricks holes over the top of the cake so that syrup will be more absorbed by the cake).
Let the cake cool completely while it absorbs the syrup.
After the cake has cooled Perelman adds a glaze made from combining and whisking until smooth:
1 c (4.2 oz) confectioners' sugar
2 T grapefruit [lemon] juice
Pinch of salt
The glaze is poured over the cake and drizzled decoratively down the sides.

January 2015: VARIATION: ORANGE POPPY SEED CAKE
Reduce the sugar to 6.6 oz
Increase the flour to 7.0 ounces
Instead of lemon, use zest of one orange
Instead of buttermilk and lemon juice, use juice of 1 orange and add enough buttermilk/milk/orange juice so liquid equals 1/3 c plus 2 T.
Add 1/2 t vanilla
Follow direction given above, then cover with orange glaze:
2 T orange juice
2 T sugar
I served this a few nights ago with a choice of a scoop of vanilla ice cream or vanilla non-fat frozen yogurt, both topped with orange fused olive oil and rosemary.
