I met my wife on a “Gourmet backpacking trip” – she brought a chocolate fondue and I brought ice cream sundaes (using dry ice for the ice cream). Â And I catered a wedding on top of Half Dome once.
High quality crackers and then, yeah, as JCH and Bonzo mention, high-quality cheeses and meats – soft cheeses on a day hike, hard cheeses for overnight trips. Â Meats – just sliced turkey and roast beef – keep a day or two just fine at modest temperatures and salami and prosciutto last a long time. Â If you accept a bit more weight, look to classics like prosciutto and melon or pairing pear or apple varieties with medium cheeses.
Polycarbonate wine glasses are light. Â Decanting wine or liquor into PET soda bottles cuts the weight in half going in (by avoiding the glass bottle) and by almost 100% while hiking out. Â Decanting very cold champagne gently into pop bottles preserves the carbonation and the whole container (champange in PET bottle) can be then be frozen and serve as cooling for other courses – like the smoked salmon and hazelnut-chocolate-torte wedding cake on Half Dome.
Jacob’s idea of hiking to a nice restaurants was tongue-in-cheek, but we did that on our honeymoon in Italy using a guidebook, “Walking and Eating in Tuscany and Umbria” that detailed hikes through hills, orchards and vinyards that ended at nice bistros and cafes. Â Lots of hilltops in Germany and Switzerland have cafes with latte bars, certainly beer and wine, sometimes more. Â At one refugio in the Italian Alps we stayed at, you could camp in the meadow and make your own ramen, but we went with the meal plan and had 4-course dinners.
