I have been using this cake recipe for some time now and we like it a lot

0.5 CUP FLOUR
2.5 CUPS SEMOLINA
1 CUP GROUND & ROASTED ALMONDS
3/4 CUP RAISINS
2 TSP BAKING POWDER
2 TSP CINNAMON
1/4 TSP SALT
2 TBSP MARGARINE
1/2 CUP CORN OIL (+ MORE IF NEEDED)
1 CUP SUGAR
3 EGGS
JUICE FROM 1 LARGE ORANGE
GRATED PEEL FROM 1 ORANGE
JUICE FROM 1/2 LEMON

Syrup
2.5 CUPS WATER (LESS IS NOT ENOUGH, MORE IS TOO MUCH)
1.5 CUPS SUGAR
1 CUP HONEY
JUICE OF 1/2 LEMON
JUICE OF 1/2 ORANGE

However I only added the orange and lemon juice lately and although the results have not changed except that the taste has improved, I wonder if I should substitute the baking powder for baking soda.
