Is your feature request related to a problem? Please describe.
Based on 'explore' view feedback: the view provides quick way to navigate through the recipe set based on a series of ingredient yes/no prompts. However, sometimes the user may have additional context of their own and would like to guide the search process by entering specific ingredients.

Describe the solution you'd like
Provide the ability for users to enter named ingredients on the 'explore' view. This could re-use the ingredient autosuggest prompt from the existing search view (homepage).
