When looking at a blank recipe (to create a recipe, use the +New Button), you will see the option to "Add Bulk" your recipe. Click on this button to add multiple lines of recipe text all at once.
A window will pop up where you can copy and paste your ingredients into the left panel, and your prep method steps into the right panel.
Use a colon [ : ] to create a header
Use parenthesis ( ) to create notes
Each separate line will be taken as a new ingredient/prep step, so be sure to hit enter after each ingredient or step.
