You could do it like this : Create a data tiddler for a recipe with a quantity associated to each ingredient. To make things easier the unit will be hardcoded in grams (or whatever you like, but always the same).
Then you can select your recipe for the week with a select widget for example (https://tiddlywiki.com/#SelectWidget), use the data of the widget in a list widget (https://tiddlywiki.com/#ListWidget) which will sum the values of each unique index accross the data-tiddlers you selected. I think you will need the count Operator (https://tiddlywiki.com/#count%20Operator), getindex Operator (https://tiddlywiki.com/#getindex%20Operator), sum Operator (https://tiddlywiki.com/#sum%20Operator).
