I like lemony tasting things. Does it make much difference when the lemon juice is added? Does it lose some of it's flavor to heat or does it hold it pretty well? I just squeeze the juice on things I want lemony right at the table.
There's almost no lapse between the adding of stuff and the eating, and since you have to wait until the sweet potatoes have cooled down enough to handle, the mash is more warm than hot before you add anything. You definitely want the lemon juice mixed in. It's not one of those dishes you just sprinkle lemon over. It's basically mashed potatoes, ya know? Everything that goes in it goes in and then you nom the finished product.
