Question

read the text.
sweet, buttery, crumbly; in a word, perfect—recipe room’s shortbread is the cookie recipe of my dreams. but baker beware: these are addictive! in fact, my friends polished off a platter of them in a matter of minutes, so be forewarned and make at least a double batch.
not only does the recipe stand on its own, but it’s also an excellent starting point for variations. i used vanilla extract the first time, with fabulous results. the next time, i added orange juice for a mouthwateringly refreshing flavor. the next time around, i plan on adding lemon zest for extra zing. i’ll bet i could substitute peppermint and that would be delicious, too.
here’s my favorite trick: i replace one - quarter cup of the flour with cornstarch to produce a softer—and absolutely scrumptious—cookie. if you’re in the mood for shortbread, you should definitely try this recipe. the possibilities are endless!
which sentence best summarizes the author’s point of view about recipe room’s cookie recipe?
this cookie recipe is worth making because it is delicious on its own, but it also allows for interesting variations.
this cookie recipe is so delicious because it includes many different types of flavorings.

Explanation:

The first option captures the author's view: the recipe is delicious (per "perfect", friends finished quickly, own attempts with vanilla etc.) and allows variations (used as starting point, plans for lemon zest, peppermint, cornstarch trick). The second option is wrong as the recipe is delicious on its own and variations are added by the baker, not included in the recipe.

Answer:

This cookie recipe is worth making because it is delicious on its own, but it also allows for interesting variations.
