grated lemon rind (in proportion to sugar) Lemon juice to make "runny" consistency. It should drip from the spoon. Spoon it right over the tops of the cakes in the jar or over the bundt cake shape. Put the lids on and screw down the rings. Everything worked fine. I tasted one of them after a few days...naturally! The cake was delicious and didn't lose any of its flavor with the substitutions. This cake is always a hit, and SO easy to make. It takes exactly one hour from start to finish! Ronda Furgatch
