You can use bottled lemon juice, but it will taste better if you squeeze it fresh. Just be sure to strain out the lemon seeds before adding the juice to your potatoes.

It’s okay if your pan isn’t exactly 13 in × 9 in (33 cm × 23 cm), but make sure there’s enough room to spread your potatoes evenly on the bottom with some space between. This will keep them from getting over-steamed and soggy. [4] X Research source
